I really like this tool and see an idea for it. As a photographer, one of the chores I have is making sure my image file has all the right SEO terms. I compound my own issue because I am an abstract photographer--images aren't always easy to determine the best fit for that. If you developed a way to upload an image and get suggestions, that would be awesome. However, do understand that artists are hypersensitive to uploading any art to be used my the AI machines for learning. It cuts our noses off despite our faces. So the best bet would be to have an opt-out clearly noted (And easy to manage by user).
