I have been to site like http://wallpaper.deviantart.com/, and in the multi-screen category i can actually find some nice wallpaper for dual screen; however, i have no idea how to do the set up so that they can be put into 2 screens, currently, it looks like 2 screens share the same wallpaper, can some one tell me how use those dual screen wallpapers?

I don't know if there's a way to span one background across two monitors, but you could always split it into two separate files, one for each monitor.

When you right click and go to wallpaper on a dual screen setup a box appears on each monitor. Select the wallpaper you wish to use on each side. If you want a spanning effect from the wallpaper you will need to edit the picture to acheive that.
