Here’s the information I received from my web expert for getting a photo of you to show up next to your forum posts, etc.
(1.) Go to http://www.gravatar.com. Click the “Get your gravatar today” button. (Ignore all the other options for site owners, WordPress users, etc.).
(2.) On the next page, you just fill out your email address to sign up.
(3.) Then they will email you a confirmation link so you can log in to their site to upload a picture. Once you add a photo to your gravatar.com account, your picture will show up on your website whenever you write forum posts, etc.
