The simpler media website CMS
The image rotation is not working in zenphoto. It seems not to be caused by unusual exif info as all linux image viewers display these pictures with correct orientation.
Also pictures are shown with incorrect orientation on album/picture detail page but when i click on the picture it is presented in an popup with correct rotation.
Nevertheless, as said before, the detail page and the gallery do not rotate pics correctly (or at all).
I use the Imagick graphics library.
