I'll use manga for an example. If I had a decent sized image of a manga comic or whatever you're meant to call them, then sync it to my iPod with iTunes, I think iTunes converts it to some dodgy file type and makes it low quality, making it so you can't zoom in very far, and all the writing is blurry/unreadable. Is there an app or a way to store/view photos in high quality. I'm jailbroken, so I can SSH photos in as well if needed.
