Any ideas on rotating photos

[Vxixz]

Hello, Im just inquiring as to if anyone has seen any free software that can rotate images to fit the htc touch pro background. That's pretty much the only function im looking for besides possibly an auto resize feature. I just am a little bit of a photographer and when i take horizontal images that id like to use as my background the only way to rotate them is through my pC. I've tried a couple of them for instance Pocketpicture and such, but i find they seem to crash when loading a large resolution image or just a high quality image.
