jgaiser got it wrong about the cover and everyone after that seems to have jumped on the cover bandwagon. It's not about the cover. It's bout the thumbnail image. This is just a really tiny image of whatever the cover image is. I've found no reason for the thumbnail image to be inside the eBook. ADE generates the cover view image from the cover image. Mobipocket Reader does the same thing. So the thumbnail image is NOT used to generate the cover image for cover view.
So what reason is there to have this thumbnail image? All it does it take up space. And in some cases it's also specified to be used int he spine so if the ePub is converted to Mobipocket, you have a link tot he thumbnail image. But you also have the cover.
So given that the thumbnail is not used for the cover image in cover view, what is it for?
