Problems with custom profile avatars?

[Callex]

Hey, I've recently been trying to upload a custom avatar for my account; the image is a .gif less than 6kb and has a 80x80 resolution. When I press upload however I get the following message:

I've also tried linking to the image via URL, and I'm given a message saying that my profile avatar has been updated. No new image is shown in my account however...

Has anyone else experienced problems like this? Is it a site issue or am I just doing something wrong?

EDIT: After using a different host for the file, I finally managed to upload it from a URL. I think I confused 'Upload Avatar from a URL' and 'Link to off-site Avatar'. Theres still an error with uploads straight from my pc however...
