it was never possible to rotate a photo after uploading - even by jobalba. The photo would need to be rotated on your own computer before uploading. However, like devilfish, this doesn't work for me any more - even rotated and saved in the new form it still only uploads to the site in the original form. It is rather annoying.
TLD, your photo above was uploaded two years ago. It would be inetresting to see if you can still upload a photo in portrait mode.
There will eventually be upgrades to the gallery which will allow photos to be rotated by the user.
