I'm building a site to connect patients to doctors. Each doctor will have a profile picture. I'm quite happy to manually maintain the profile pictures as there won't be that many doctors nor will they have a need to change their picture very often, if at all.

I thought of using Gravatar to host all these profile pictures. The idea is to create a single Gravatar account then keep adding email addresses to it in the form [email protected] and associating each one with a new image.

Does anyone know, however, if I will run into any per-account limit? If so, it wouldn't be feasible because I would end up with a bunch of Gravatar accounts instead of just the one.
