Adding Product attributes from Magento admin is very easy and you can add your desired attribute type from the list of catalog Input types for product Attributes.
But if you want to add custom image upload attributes and if you choose `Media Image` attribute then it will display inside Images and Video Group for the Product edit form and on front-end it will also come inside the product gallery section images.
Let's start by creating a custom module.

<?php namespace Magelearn\ProductImage\Setup; use Magelearn\ProductImage\Model\Product\Attribute\Backend\ImageUploader as ImageUploaderBackend; use Magento\Framework\Setup\ModuleContextInterface; use Magento\Framework\Setup\ModuleDataSetupInterface; use Magento\Framework\Setup\InstallDataInterface; use Magento\Eav\Setup\EavSetupFactory; /** * Class InstallData * @package Magelearn\Productattachement\Setup * * @codeCoverageIgnore */ class InstallData implements InstallDataInterface { /** * @var EavSetupFactory */ protected $_eavSetupFactory; public function __construct( EavSetupFactory $eavSetupFactory ) { $this->_eavSetupFactory = $eavSetupFactory; } /** * {@inheritdoc} * @SuppressWarnings(PHPMD.CyclomaticComplexity) * @SuppressWarnings(PHPMD.ExcessiveMethodLength) * @SuppressWarnings(PHPMD.NPathComplexity) */ public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) { $eavSetup = $this->_eavSetupFactory->create(["setup"=>$setup]); $eavSetup->addAttribute( \Magento\Catalog\Model\Product::ENTITY, 'product_label_image', [ 'group' => 'Content', 'type' => 'varchar', 'label' => 'Product Label Image', 'input' => 'text', 'backend' => ImageUploaderBackend::class, 'frontend' => '', 'class' => '', 'source' => '', 'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL, 'visible' => true, 'required' => false, 'user_defined' => true, 'default' => '', 'searchable' => false, 'filterable' => false, 'comparable' => false, 'visible_on_front' => true, 'unique' => false, 'apply_to' => 'simple,configurable', // applicable for simple and configurable product 'used_in_product_listing' => true ] ); } }Now, as per highlighted code above, we will add our backed class.
<?php declare(strict_types = 1); namespace Magelearn\ProductImage\Model\Product\Attribute\Backend; use Magelearn\ProductImage\Model\ImageIO; use Magento\Eav\Model\Entity\Attribute\Backend\AbstractBackend; class ImageUploader extends AbstractBackend { /** * @var ImageIO */ private $imageIO; /** * ImageUploader constructor. * * @param ImageIO $imageIO */ public function __construct( ImageIO $imageIO ) { $this->imageIO = $imageIO; } /** * @inheritdoc */ public function beforeSave($object) { $attribute = $this->getAttribute(); $attrCode = $attribute->getAttributeCode(); $value = $object->getData($attrCode); if ($value && is_array($value) && isset($value[0])) { if (!isset($value[0]['id'])) { $object->setData($attrCode, null); } elseif (isset($value[0]['url']) && $this->isWysiwygPath($value[0]['url'])) { $object->setData($attrCode, $value[0]['url']); } elseif (isset($value[0]['file'])) { $object->setData($attrCode, $value[0]['file']); } } return parent::beforeSave($object); } /** * @inheritdoc */ public function afterSave($object) { $value = $object->getData($this->getAttribute()->getName()); if ($value && is_array($value) && isset($value[0]) && isset($value[0]['url'])) { $imagepath = (string)$value['0']['url']; if($this->isWysiwygPath($imagepath)) { $this->imageIO->moveFileFromTmp($imagepath); } } elseif ($value && !$this->isWysiwygPath($value)) { $this->imageIO->moveFileFromTmp($value); } return $this; } /** * @inheritdoc */ public function afterLoad($object) { $attrName = $this->getAttribute()->getName(); if ($value = $object->getData($attrName)) { $isWysiwygPath = $this->isWysiwygPath($value); $object->setData( $attrName, [ [ 'name' => $isWysiwygPath ? $this->getFileNameFromPath($value) : $value, 'url' => $this->imageIO->getImageUrl($value, $isWysiwygPath), 'type' => 'image', ] ] ); } return parent::afterLoad($object); } /** * @param string $path * * @return bool */ public function isWysiwygPath(string $path): bool { return (bool) strpos($path, 'wysiwyg'); } /** * @param string $path * * @return string */ private function getFileNameFromPath(string $path): string { $parts = explode('/', $path); return end($parts); } }
<?xml version="1.0" encoding="UTF-8"?> <form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd"> <fieldset name="content"> <field name="product_label_image"> <argument name="data" xsi:type="array"> <item name="config" xsi:type="array"> <item name="dataType" xsi:type="string">string</item> <item name="label" xsi:type="string" translate="true">Product Label Image</item> <item name="visible" xsi:type="boolean">true</item> <item name="allowedExtensions" xsi:type="string">jpg jpeg gif png svg</item> <item name="maxFileSize" xsi:type="number">2097152</item> <item name="formElement" xsi:type="string">imageUploader</item> <item name="previewTmpl" xsi:type="string">Magento_Catalog/image-preview</item> <item name="elementTmpl" xsi:type="string">ui/form/element/uploader/uploader</item> <item name="dataScope" xsi:type="string">product_label_image</item> <item name="sortOrder" xsi:type="number">40</item> <item name="uploaderConfig" xsi:type="array"> <item name="url" xsi:type="url" path="productimage/image/upload"> <param name="target_element_id">product_label_image</param> <param name="type">image</param> </item> </item> <item name="validation" xsi:type="array"> <item name="required-entry" xsi:type="boolean">false</item> </item> </item> </argument> </field> </fieldset> </form>
To make this uploaderConfig URL working properly, we will add etc/adminhtml/routes.xml file.
<?xml version="1.0" encoding="UTF-8"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd"> <router id="admin"> <route id="productimage" frontName="productimage"> <module name="Magelearn_ProductImage" /> </route> </router> </config>
Now note that we have added this `product_label_image` field as an input type 'text'.
So we need to modify this field to display it properly on product edit form.
For that add file at Magelearn/ProductImage/etc/adminhtml/di.xml
<?xml version="1.0" encoding="UTF-8"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <virtualType name="Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\Pool"> <arguments> <argument name="modifiers" xsi:type="array"> <item name="add_product_image" xsi:type="array"> <item name="class" xsi:type="string">Magelearn\ProductImage\Ui\DataProvider\Product\Form\Modifier\Image</item> <item name="sortOrder" xsi:type="number">200</item> </item> </argument> </arguments> </virtualType> </config>
Now as per highlighted code above,
Add Magelearn/ProductImage/Ui/DataProvider/Product/Form/Modifier/Image.php file.
<?php declare(strict_types = 1); namespace Magelearn\ProductImage\Ui\DataProvider\Product\Form\Modifier; use Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\AbstractModifier; class Image extends AbstractModifier { /** * @param array $data * * @return array */ public function modifyData(array $data): array { return $data; } /** * @param array $meta * * @return array */ public function modifyMeta(array $meta): array { if (isset($meta['content']['children']['container_product_label_image'])) { $meta['content']['children']['container_product_label_image']['children'] = array_replace_recursive( $meta['content']['children']['container_product_label_image']['children'], [ 'product_label_image' => [ 'arguments' => [ 'data' => [ 'config' => [ 'visible' => 0, ], ] ] ] ] ); } return $meta; } }
Now we will give our imageUploader configuration for our custom backend model.
For that Add a file at etc/di.xml
<?xml version="1.0" encoding="UTF-8"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <type name="Magelearn\ProductImage\Model\Product\Attribute\Backend\ImageUploader"> <arguments> <argument name="imageIO" xsi:type="object">Magelearn\ProductImage\Model\Virtual\ImageIO</argument> </arguments> </type> <type name="Magelearn\ProductImage\Controller\Adminhtml\Image\Upload"> <arguments> <argument name="imageIO" xsi:type="object">Magelearn\ProductImage\Model\Virtual\ImageIO</argument> </arguments> </type> <virtualType name="Magelearn\ProductImage\Model\Virtual\ImageIO" type="Magelearn\ProductImage\Model\ImageIO"> <arguments> <argument name="baseTmpPath" xsi:type="string">catalog/tmp/product/labels</argument> <argument name="basePath" xsi:type="string">catalog/product/labels</argument> <argument name="allowedExtensions" xsi:type="array"> <item name="jpg" xsi:type="string">jpg</item> <item name="jpeg" xsi:type="string">jpeg</item> <item name="png" xsi:type="string">png</item> <item name="svg" xsi:type="string">svg</item> <item name="gif" xsi:type="string">gif</item> </argument> </arguments> </virtualType> </config>
Now as per highlighted above code, we will add our controller and imageUploader file.
Add file at Controller/Adminhtml/Image/Upload.php
<?php declare(strict_types = 1); namespace Magelearn\ProductImage\Controller\Adminhtml\Image; use Exception; use Magelearn\ProductImage\Model\ImageIO; use Magento\Backend\App\Action; use Magento\Backend\App\Action\Context; use Magento\Framework\App\Action\HttpPostActionInterface; use Magento\Framework\Controller\ResultFactory; class Upload extends Action { /** * @var ImageIO */ private $imageIO; /** * Upload constructor. * * @param Context $context * @param ImageIO $imageIO */ public function __construct( Context $context, ImageIO $imageIO ) { $this->imageIO = $imageIO; parent::__construct($context); } /** * @return mixed */ public function _isAllowed() { return $this->_authorization->isAllowed('Magelearn_ProductImage::upload'); } /** * @inheritdoc */ public function execute() { $imageId = $this->_request->getParam('param_name', 'product_label_image'); try { $result = $this->imageIO->saveFileToTmpDir($imageId); $result['cookie'] = [ 'name' => $this->_getSession()->getName(), 'value' => $this->_getSession()->getSessionId(), 'lifetime' => $this->_getSession()->getCookieLifetime(), 'path' => $this->_getSession()->getCookiePath(), 'domain' => $this->_getSession()->getCookieDomain(), ]; } catch (Exception $e) { $result = [ 'error' => $e->getMessage(), 'errorcode' => $e->getCode() ]; } return $this->resultFactory->create(ResultFactory::TYPE_JSON)->setData($result); } }
Add file at Model/ImageIO.php
<?php namespace Magelearn\ProductImage\Model; use Exception; use Magento\Framework\App\Filesystem\DirectoryList; use Magento\Framework\Exception\LocalizedException; use Magento\Framework\Exception\NoSuchEntityException; use Magento\Framework\UrlInterface; class ImageIO { const BASE_TMP_PATH = "catalog/tmp/product/labels"; const BASE_PATH = "catalog/product/labels"; const ALLOWED_EXTENSIONS = ['jpg', 'jpeg', 'gif', 'png', 'svg']; /** * @var string */ public $baseTmpPath; /** * @var string */ public $basePath; /** * @var string[] */ public $allowedExtensions; /** * @var \Magento\MediaStorage\Helper\File\Storage\Database */ private $coreFileStorageDatabase; /** * @var \Magento\Framework\Filesystem\Directory\WriteInterface */ private $mediaDirectory; /** * @var \Magento\MediaStorage\Model\File\UploaderFactory */ private $uploaderFactory; /** * @var \Magento\Store\Model\StoreManagerInterface */ private $storeManager; /** * @var \Psr\Log\LoggerInterface */ private $logger; /** * ImageUploader constructor. * @param \Magento\MediaStorage\Helper\File\Storage\Database $coreFileStorageDatabase * @param \Magento\Framework\Filesystem $filesystem * @param \Magento\MediaStorage\Model\File\UploaderFactory $uploaderFactory * @param \Magento\Store\Model\StoreManagerInterface $storeManager * @param \Psr\Log\LoggerInterface $logger * @throws \Magento\Framework\Exception\FileSystemException */ public function __construct( \Magento\MediaStorage\Helper\File\Storage\Database $coreFileStorageDatabase, \Magento\Framework\Filesystem $filesystem, \Magento\MediaStorage\Model\File\UploaderFactory $uploaderFactory, \Magento\Store\Model\StoreManagerInterface $storeManager, \Psr\Log\LoggerInterface $logger ) { $this->coreFileStorageDatabase = $coreFileStorageDatabase; $this->mediaDirectory = $filesystem->getDirectoryWrite(DirectoryList::MEDIA); $this->uploaderFactory = $uploaderFactory; $this->storeManager = $storeManager; $this->logger = $logger; $this->baseTmpPath = self::BASE_TMP_PATH; $this->basePath = self::BASE_PATH; $this->allowedExtensions = self::ALLOWED_EXTENSIONS; } /** * @param $imageName * @return mixed * @throws LocalizedException */ public function moveFileFromTmp($imageName) { $baseTmpPath = $this->getBaseTmpPath(); $basePath = $this->getBasePath(); $baseImagePath = $this->getFilePath($basePath, $imageName); $baseTmpImagePath = $this->getFilePath($baseTmpPath, $imageName); try { $this->coreFileStorageDatabase->copyFile( $baseTmpImagePath, $baseImagePath ); $this->mediaDirectory->renameFile( $baseTmpImagePath, $baseImagePath ); } catch (Exception $e) { throw new LocalizedException( __('Something went wrong while saving the file(s).') ); } return $imageName; } /** * @return string */ public function getBaseTmpPath() { return $this->baseTmpPath; } /** * @param $baseTmpPath */ public function setBaseTmpPath($baseTmpPath) { $this->baseTmpPath = $baseTmpPath; } /** * @return string */ public function getBasePath() { return $this->basePath; } /** * @param $basePath */ public function setBasePath($basePath) { $this->basePath = $basePath; } /** * @param $path * @param $imageName * @return string */ public function getFilePath($path, $imageName) { return rtrim($path, '/') .

'/' . ltrim($result['file'], '/'); $this->coreFileStorageDatabase->saveFile($relativePath); } catch (Exception $e) { $this->logger->critical($e); throw new LocalizedException( __('Something went wrong while saving the file(s).') ); } } return $result; } /** * @return string[] */ public function getAllowedExtensions() { return $this->allowedExtensions; } /** * @param $allowedExtensions */ public function setAllowedExtensions($allowedExtensions) { $this->allowedExtensions = $allowedExtensions; } public function saveMediaImage($imageName, $imagePath) { $baseTmpPath = $this->getBaseTmpPath(); $basePath = $this->getBasePath(); $baseImagePath = $this->getFilePath($basePath, $imageName); $mediaPath = substr($imagePath, 0, strpos($imagePath, "media")); $baseTmpImagePath = str_replace($mediaPath .

After adding the above code, custom image upload button will be displayed at Product Add/Edit form.
Now we will check how to add this product custom image attribute`product_label_image` at frontend.
For that add layout file at view/frontend/layout/catalog_product_view.xml
<?xml version="1.0"?> <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <body> <referenceContainer name="product.info.main"> <block class="Magento\Catalog\Block\Product\View" name="product.info.product_label_image" template="Magelearn_ProductImage::display-product-label-image.phtml" /> </referenceContainer> </body> </page>
Also at template file at view/frontend/templates/display-product-label-image.phtml
<?php $product = $block->getProduct(); $product_label_image = $product->getProductLabelImage(); if(is_array($product_label_image) && isset($product_label_image['0']['type'])) { if($product_label_image['0']['type'] == 'image') { $product_label_image_name = $product_label_image['0']['name']; $product_label_image_url = $product_label_image['0']['url']; } } ?> <?php if ($product_label_image_url && $product_label_image_name): ?> <div class="product_label_image"> <label class="label"><span><strong><?= __('Product Label Image: ')?></strong> <img src="<?= $block->escapeHtml($product_label_image_url) ?>" alt="<?= $block->escapeHtml($product_label_image_name) ?>"> </span></label> </div> <?php endif; ?>
