I had this problem when the site first switched to the new version of IPB, but it appears it's still happening.

When I go to upload a new avatar image it says the upload has failed. Any reason why this is happening?

The image is within the limits allowed, and now I consequently have no avatar image at all

Upload it on photobucket and then link it via that in the other 'upload' box. Should then work.

Ta very much

The upload feature should work now. Please let us know if you are still having issues.
