I enter as much stock information as I can about the products I sell, but sometimes I end up submitting an associated stock picture only to notice a watermark from another site is on it after submission, or it's for the wrong edition of the product I submitted. Whether it's my or someone else's submissions I cannot rectify these mistakes as things are currently; once a picture is uploaded that's it.
Since I can edit all other aspects of the product information, it would be quite helpful to also be allowed to submit a replacement stock picture if I feel I can offer a better one than what is currently there.
