Why have random numbers and letters been added to my image name?

The reason that random numbers and letters have been added to the end of your image name is that there are 2 or more images that would have had the same name after editing with our Bulk Image Edit app.

Shopify does not allow multiple images to have the same name, so if Bulk Image Edit is used to change the file names and any of them have the same name, Shopify will add a suffix to the duplicates in order to prevent having the same name. Depending on the case, this is a number (such as -2) or a random string of letters and numbers.

For example, here we have a task which has renamed 1 product with 3 images using the template [product_title], without the image position:

You can see from the screenshot that the task renames the third image from tshirt-black.jpg to Classic-Cotton-T-Shirt.jpg, but that name is already used by the first image.

When we check the images again, we can see that a suffix has been added to the duplicates: the file names are Classic-Cotton-T-Shirt.jpg, Classic-Cotton-T-Shirt-2.jpg and Classic-Cotton-T-Shirt-3.jpg

It is recommended that you add a unique identifier to your image names, such as option names, or image position numbers when editing your image names.
