I installed the screen saver hack today on me KT, everything went great untill i put the new screensavers onto my kindle.
The First two displayed correctly but after that it would only show the last page displayed.
It turned out that the wallpapers i had downloaded were the problem, They were all png files of the right dimensions but they were 24bit files, even tho they were desaturated.
I'm so glad i checked before i came running for Help.
i ran everything through GIMP, and now i'm a happy bunny.
Now to turn some of my own photos into wallpapers.
Thanks for such a great Hack.
