I've been wrestling with this for a while.. I've added some of my old Epub books , and noticed the artwork wasn't the correct size to display properly.. I resized the images and added them to the epub files "get info / artwork section" and sync'd They show great in itunes but they are always the old artwork on the ipad. I've deleted the files from the ipad , readded, tried deleting from itunes entirely and readding then resyncing.. No go.. Tried renaming the epub files and readding to itunes.. No go.. It keeps using the old artwork. I deleted all of the cache folders on the computer, but I'm guessing there is some kind of cache on the device.. Is there anyway to make this artwork update?
