text: how do you make a wallpaper for your desktop?   hm... do you mean use any image as a wallpaper? or do you mean to actually go about creating an image to use?  use another image: right click on the image in a browser and click on "use as wallpaper". make your own: open your image creation/editing program (ms paint, photoshop, paint shop pro, etc.), and check the specifications of your desktop (800x600? 1024x768? other variant?), and create a canvas of that size (in pixels). then randomly do things to the canvas. draw a picture, make cool effects, cut 'n paste images, etc. just go crazy. then save the image, open the program/folder from which you change wallpapers and select that image. click apply, then ok.
