If you like them, but want to, say, add your name and phone number to them...

These default pictures can be found in the following location on many Boox devices:
[root]/system/framework/framework-res.apk
- open APK with zip archive viewer (probably best on a PC)
- image location inside APK: assets/images
To edit, use the graphics program of your choosing (
GIMP is free)
To set as your screensaver, put the pictures on your device first--I suggest making or using a folder in the Storage/Downloads/Onyx folder called Sceensavers, since the Onyx folder is already set-up to store some system stuff, like Icons. Then use the devices built-in Storage app (on the left menu of the 'home' screen) to navigate to the picture > long press the picture > and hit the 'Set as screensaver' option at the bottom of the popup.
You can set 3 different screensavers and one off-screen picture, or reset all to factory setting from the 'Set as screensaver' screen.
