Why do my uploaded images get random sequences added to their names?

Hey!

I’ve recently noticed that all images names that I upload to our site get a bizarre sequence of letters and numbers added to their file name.

Example:

Original image name: green_tshirt

Name after uploaded to site: green_tshirt_ab8290ca-4e6b-4813-af4a-cc2a150a4a01

Our SEO expert has pointed this out and said it has a negative affect on our site. Does anyone know why this happens and how I can stop it from happening in the future?

Thanks!

this is by shopify and states that there is another file with that name so they generate a unique one
