- Open the picture in Safari. This is likely not a default image viewer, so Control-click on the image and use the Open With menu. As long as it's a common format -- JPEG, TIFF, PNG, etc -- Safari should automatically appear. You can also drag the image onto Safari's icon in the Dock, which is even simpler.
- In Safari, Control-click on the image and select Use Image as Desktop Picture.
[robg adds: While this is indeed a quick way to set a single image as a desktop background, it doesn't actually add the image to an existing collection; it merely sets the selected image as the desktop background. If you want to add the picture to a rotating set of images, you'll have to do it yourself. I do this by specifying my own folder of images to use for desktop images, then just adding pictures to that folder.]
