Problem uploading to my profile


Ok im having a problem with uploading an image to my profile.
For some reason everytime i try to upload an image it appears if its uploading the file, but it doesnt get uploaded. All i get is a small thumbnail which doesnt load, like the image doesnt exist on the server.

Im trying to upload a 800 x 600 jpg and ive tried using both firefox and ie6 - both are giving me the same prob.

Its definitely a pain not being able to show my work.
My username for my profile is Scorpiontail in case you need to know.
