Making pictures larger..

[The Giver]

I got my iBook 5 months ago and I still don't know how to make a small copied picture from the internet big enough to have good detail as my background... cuz when I try to make it fill the screen, its really blurry.

If the image that you're using is low-resolution (which it would be if it was a small image that you copied), it will appear blurry when you enlarge it. There won't be enough pixels to form a detailed larger image. If you want a crisp-looking desktop image, you'll want to search for high-resolution images (preferably 1024x768, but 800x600 can be acceptable too).
