Sorry, splizzle but your idea won't work for me. I want to place this theme on site. Everybody can have any wallpaper.
About DeViLbOi idea... i've spend some time on it and that's what i've figured out:
I'm gonna need lswchanger-1.2 (it gives bang to change wallpaper) and comdlgls-0.7 (it provides "open file" dialog). Let's say "" is wallpaper you want(addres to picture).
1. User clicks button that open "open file" dialog and chooose
2. Wallpaper is changed with
3. is send to label and shows miniature
... but how make label (miniature) to check if wallpaper is changed automaticly??
I hope this is understand-able :)
