এখানে একটি সহজ সমাধান যা জেএস লোড করার সময় পণ্যের বেস চিত্রটি প্রদর্শিত হতে পারে। আপনার থিমে নিম্নলিখিত ফাইলটি তৈরি করুন:
{theme_dir}/Magento_Catalog/templates/product/view/gallery.phtml
ধারণ করে:
<div class="gallery-placeholder _block-content-loading" data-gallery-role="gallery-placeholder">
<div data-role="loader" class="loading-mask">
<div class="loader">
<img src="<?php echo $block->getGalleryImages()->getFirstItem()->getData('medium_image_url') ?>" style="max-width: 100%; max-height: 100%">
<img src="<?php /* @escapeNotVerified */ echo $block->getViewFileUrl('images/loader-1.gif'); ?>"
alt="<?php /* @escapeNotVerified */ echo __('Loading...') ?>">
</div>
</div>
</div>
<!--Fix for jumping content. Loader must be the same size as gallery.-->
