Yes, and that's what I'm talking about the 2 links above -- guide how to change boot image (boot image -- is not a picture, it's like DVD image -- the copy of entire bootable disk).
Also there's some info how to change bootable animation (bootanimation -- animated pictures which shown while android loading), which not able to be shown on e-ink screen.

But the image which U called "shutdown image on e-ink" is what you can change as described here http://www.entourageedge.com/forums/...roid-guru-here
