Does anyone know how to get panoramic pictures or tall pictures to fit on the desktop background? I don't want to resize them, and lose quality, I just want them to fit the picture and put black bars on the sides or top and bottom. All the options in system preferences just distort the pictures or end up lopping off the sides or tops. Are there any third party programs or Mac OS X tweaks anyone knows of to give users that option. It bugs the crap out of me.
