It can be an ugly mess if you start importing product images into Magento 2 one by one. Here are two simpler ways you can upload multiple images for Magento 2 products in bulk:
You can also save yourself the trouble completely. With Magento 2 Product Attachments module, you ‘ll be able to add a range of files to your product pages.It also has the add-on that allows using API to upload your files to Magento 2.
The Magento 2 product images import will take place in two steps here.
Upload the image files to the default folder for importing product images. Normally, you may use this path: pub/media/import. However, a different folder can be specified for the files on Magento server and the new path can be defined during the importing process.
Then you should enter the name of each image file that needs to be imported on the relevant row in the CSV data (by SKU, and image type: base_image, small_image, thumbnail_image, additional_image).
Check if a correct path is specified before each image file name to the import directory. E.g.: pub/media/import/image.jpg;
Carry out instructions in the importing products section before filling in the Images File Directory field;
Then add the path to the Magento folder (in which you upload the media) to the beginning of the Images File Directory field and go on importing product image files. [Admin Panel>System>Import>Product>Import>File to Import]:
If you cannot upload images to Magento product page and get an error during the importing process, check the path for the image location.
The product images import will take place in two steps as well. For the Step 2 follow the instructions from the Import images to CSV from the local server shown above.
Upload the image files to be imported to the chosen folder on the external server. Fill in the complete URL for each image file in the CSV data (by image type: base_image, small_image, thumbnail_image, additional_image). E.g.: https://example.com/images/image.jpg.
Once you've performed all the changes with the Magento product images, clear the cache.
Show Magento product image in the popup for grouped, configurable and bundle products with the AJAX Shopping Cart extension.
