I know that SmugMug is primarily oriented at photographers. I have an account there, with some hobby pictures of mine, and I like the experience. I don't have other accounts to upload pictures to, for example no DeviantArt account. It would be convenient for me to upload other image files to SmugMug, for example fractal art I have generated, so I don't spread my pictures between multiple accounts.
Is it intended and required that SmugMug accounts contain photographs only? Or is it just targeted at photographers, but allowing the user to add a gallery of other types of digital art? Would I break the TOC agreement if I upload a non-photographic image in my gallery?
