Image naming convention for Stability AI images

Dear Szabi, When I generate Stability AI images using the Existing Content Editor, the naming convention for the images is a number. What course of action would you recommend to autoconvert the images to an SEO friendly name (or another solution)? I would also be interested in knowing this in connection with an Amazon S3 upload. Also the image size is quite big per default with around 2mb and in png format. WP does shrink it down to about 500kb but that is still pretty big as opposed to JPG. Any tips would be greatly appreciated. Thank you.
