I need to insert ATL tag for catalog products images programmatically. Is there any way to do it?

You can do this via the API interface Magento\Catalog\Api\ProductAttributeMediaGalleryManagementInterface. You can add the image via the create() method, or update an existing entry via the update() method. Both methods require an instance of \Magento\Catalog\Api\Data\ProductAttributeMediaGalleryEntryInterface, this interface has the setLabel() function that allows you to set the ALT tag for a product image.

I'm using a custom function to create images, it uses the above interfaces as factories. Updating an existing label/ALT tag works in the same way, but then using the update() function.

 * Add image to product by SKU
public function addImage(
    string $sku,
    string $filePath,
    array $imageTypes,
    string $destinationName,
    string $label = '',
    bool $disabled = false
): void {
    // Basic image data
    $data = file_get_contents($filePath);
    $base64 = base64_encode($data);
    $pathInfo = pathinfo($filePath);
    $fileExtension = strtolower($pathInfo['extension']);

    // Create media image
    $mediaImage = $this->mediaGalleryFactory->create();

    // Create content
    $content = $this->imageContentFactory->create();

    // Assign content to media and save image to product
    $this->mediaGalleryManagement->create($sku, $mediaImage);


public function __construct(
    ImageContentInterfaceFactory $imageContentFactory,
    ProductAttributeMediaGalleryManagementInterface $mediaGalleryManagement,
    ProductAttributeMediaGalleryEntryInterfaceFactory $mediaGalleryFactory,
) {
    $this->mediaGalleryFactory = $mediaGalleryFactory;
    $this->mediaGalleryManagement = $mediaGalleryManagement;
    $this->imageContentFactory = $imageContentFactory;

You can set the store view using the setCurrentStore($storeCode) function from StoreManagerInterface
