Why won't this avatar work?

Why won't this work for my avatar? It's 100x100 and not that big.

I tried them both, Annie, and they worked fine for me. Double-check that they are in either .gif or .jpg format when you upload them.

Okay, uploading it worked. I was trying to link to it. I dunno why that wasn't working.
