I doubt everyone looks at the built-in FAQ and I know people are still new to forums. So here's how to get an image beside your username.

First go to your Profile.


Hit the Browse button and find the desired image. Remember, 150 x 150 pixels is the limit.


After that...


There.

If any assistance is needed to resize an image, post the URL of the image here and the moderators or admins will (likely) be happy to do it for you. Photobucket resizing feature can also be a good alternative.

Thanks for the Avatar how-to! Great picture of Zack btw!
