Smugmug Avatar Links

Any smugmug users here having issues with the avatar hosting link feature? I've recently tried to update my avatar by using a direct link and I get a invalid URL message. The strange part is that it works in smugmug's forum, but not in any other forum.

Any other smugmug users out here experiencing this issue or can anyone advise me what I'm doing wrong?

I opened a zenfolio and flickr account and both of those links work correctly through POTN.

Any ideas?

You can upload an avatar directly to POTN,. no need to host it off site.

... in fact, this is the problem, not SmugMug,. I don't think you can host your POTN avatar off site.
