Hi @manpreetwebcefz,

What if you create a file to be improted with something like:

sku;website_id;additional_images;additional_image_labels
BB142;1;/1/7/1700x700x380mm-round-single-ended-bath-front-view-bb142-v5001.jpg,/1/7/1700x700x380mm-round-single-ended-bath-close-up-view-bb142-v5000.jpg,/1/7/1700x700x380mm-round-single-ended-bath-zoomed-out-view-bb142-v5001.jpg,/1/7/1700x700x380mm-round-single-ended-bath-dimensions-i2-bb142-v5000.jpg;,Test image 1,,Test image 4

(The example is from this bug report: https://github.com/magento/magento2/issues/9120 )

@Damian Culotta  If the image save with image name like consider mobile so that image save with mobile.jpg then upload to server, whenever i google image search if keyword and name of the image are same occurred on the google page. Am i right? is it alt tag do the same thing?

Hi @GTA_giri,

Sorry but I'm not sure if I understand your question and the relation with the CSV example.

Can you explain me with a specific example?
