As I understand things. If you resize an image on your computer using photoshop to 1024x768 then it will look fine on the iPads screen, but if you try and zoom in (multi touch) then you won't see any more quality in the image (as you would of course expect) If you try and sync a MASSIVE file to the iPad then there will be more quality to zoom in and see on the iPads screen. But I don't expect the iPad (when you sync with iTunes) does keep a MASSIVE image at it's same size. I guess some resizing is done to avoid storage memory being wasted. I wondered if anyone knew the real X/Y image size that iTunes/iPad will resize images to when you sync some very large pictures onto the device.
