You can copy pictures from your computer and set them as wallpaper. To do this just connect the Blackberry to your computer and then open Blackberry Desktop Manager and select Media Manager. From media manager you will be able to move picture from the computer to device memory or media card. Just be careful not to copy too many pictures as the 8800 doesn't have a media card as standard and pictures will consume device memory. Once the pictures are on your device open "Media" and select "Pictures" and select and open an image, then press the menu button and select "Set As Home Screen Image".
