I've made a Combat Arms theme with all the pictures that you can get.
Extract it and then double click it.
Your desktop background will change every 10 Seconds with a new Combat arms wallpaper.
I'm not sure if this will work for Windows XP/Vista
But I know it will work for Windows 7 99.9%
Please leave a comment if it does/doesn't work for Vista and XP or just vote in the poll.
Dont forget to press thanks

Now for all XP users this didn't work so I've got 9 Combat Arms wallpapers that were in the Theme.
