I was going to reply to tell you to use the rotate button, but was shocked to find that it doesn't do anything. Apparently, this is a "known issue" and has been since 2006 - so don't hold your breath on a fix. Seems like fairly basic functionality, but who knows.edit: if you need to rip through a folder of images, you can use the PIL Python library (example). Basically just open, rotate, save.
