The issue should be fixed now. =) if you still see them upside down, simply try clearing your browser's cache, performing a clean refresh (Ctrl+R) of the page, and then logging out, and back in.

Could you please write a pm to me with the url of the upside down images? We can investigate it further with this information. Thanks!


Edit: Inkpanther already gave me a lot of urls. =) We are looking further into the issue.

Not a coincidence. =)

The issue has been fixed and your avatars will revert to their normal state. However, this can take some time, if you can't wait then simply upload your avatar again.
