When I sync my photos with the iPod Touch, the photos are put on as very low quality. They do not even look good at full screen size and do not cope with zooming in to see details.
I can't find a setting in iTunes to control how match it compresses the photos.

You may want to try a re-sync if you recently updated to iOS 4.x
