Hello everyone !
Seeing as It took me some time to find, and I couldn't see a thread about it, I've decided to share my way of finding compatible Screensavers for the Kindle:
1.

This guy/gal has a few screensavers adapted to the kindle, so Hurray for him/her !
2. Go to Google Image -> Search Tools -> set color : Black and white ; set size -> exact size -> 758 large, 1024 high.
Then search for whatever kind of image you want. They should all be in the correct format.
Hope I helped !
