I just put up a few shots that you can use on your K1/K2 or any other reader which uses images as sort of a screen saver when the device goes into sleep mode.
Just visit the gallery link below:

If you have a K1/K2 and are not sure how to use your own creen saver images here is a link to the MR Wiki article for doing just that:

Not sure about other readers.
Hope there is an image or two you might want to grab...if not I will add as many as allowed when time permits. I might add a link to another gallery where you could grab the full color versions and/or pretty much any size you want. Anyway, have fun and maybe start your own screen saver gallery as well...post the links in this thread if ya want to save on clutter?
