Well... What I do is just right click a GIF that I want. Then click "View Image Info". A little window should pop up and there will hopefully be a button that says "Save As". Click it. Save it to your desktop or where ever you want. So, you just have to go to where you edit your BL Forums profile information. Click browse, and finish the rest just as you would to make your avatar a picture. Also I have Windows XP Media Center Edition if that would have to do with any of this.
