Apple’s Conflicting ePub Cover Dimension Messages

As I mentioned in the article about tablets changing the eBook marketplace, Apple is upping its cover image requirements – to 1400 pixels across on the shortest side.  You can even see this using iTunes Producer:

Okay, so not a big deal, right?  Just enlarge all your images…

Oh.  Wait.

So, it has to be 1400 pixels…but not more than two million pixels total…[bites tongue, does math in head]

So to satisfy both these requirements, your cover image (in the ePub) should be 1400 pixels by 1428 pixels.

A square.

I’m hoping someone at iTunes will see this and get it resolved.
