I've been trying to change my avatar this evening. I've downsized the photo to 64 pixels by 64 pixels as requested, it's a jpg format and it keeps telling me that I don't have permission! Any ideas? I've checked and rechecked the size and that its the avatar and not personal photo option that I'm using but now I'm stumped. Managed to change my signature no problem but this is driving me nuts!

Is the file size less than 20Kb and a .jpg format

O_D

Aha! that was the problem, i'd resized pixels but it was still 39kb - thanks for that!
