My site's on Omeka 1.5.1 at http://music-scholars.net. At some point (possibly with a plugin no longer present), I somehow associated an image/gravatar with my own account, so it shows up beside my Commenting entries. I'm happy to have account images like that available and used that way. However, I can't for the life of me see where a new user, for example, would even add such a thing (or opt not to, for example). What am I missing? I don't have much discussion seeded on the site yet, so see: http://music-scholars.net/items/show/49.
