Weird Avatar/Profile Pic

Hi,  I sent a message via the "contact" button, but wanted to follow up with a screen shot so you could see what I'm talking about.  This person's profile pic shows up as enormous letters and numbers.  I'm using Firefox.  Doesn't happen with anything else on the site.  It looks like it's the file name for the image?

Anyway, wanted to let you know.  When her post is at the top, where the popular threads are listed, it kind of takes over the site LOL.
