Tired of uploading photos everywhere you create an account ? Then use Gravatar.

Your Gravatar is an image that follows you from site to site appearing beside your name when you do things like comment or post on a blog. Avatars help identify your posts on blogs and web forums, so why not on any site?

Manage your profile image in one place an update automatically all your profiles.

This works particularly well in forums and blogs contexts. You can even use their API to integrate it on your own site.
