What if we were to make this option available to everyone in their profile and allow each and every person on the board have a customized icon? -- whatever they'd prefer to have beside their name in the postbit.
While it's no deal to actually have that happen, the real problem comes in when the user may use an image larger than such and such height and width. How can this be limited to or resized only to.. say, 20x20?
<edit>
20x20 without using <img height= width=>.
