I have done several zenphoto installations but am encountering a problem with a recent implementation that I can't seem to get around.

In the image-overview it states per image it wants to rotate the image 90% but it doesn't do the job after I hit save. Well, it did some but not all, no matter how many times I hit save.

I purge the cache and all that already. Any hints?

Couold you clarify. Is the radio button for rotation set at 90 degrees? If so and the image is not correctly rotated you should try setting the rotaion to a different value that would result in a correct rotation.

yeah - the rotation was set for 90% but after clicking save it didn't rotate. Changing the value wasn't possible either. But I found out I had not switched on the button "Auto rotate images" in options and after clearing cache it worked fine. Thanks!
