KoolBreeze, good question. You could save it as Kelly says, but you'd have to put it up online again to have it show in your blog or wherever. Since it's already online, it's probably easier to right click and choose "copy image location." This will give you the existing online location of each image, and you can insert it as an image, like this:

Just delete the two spaces, which I put in to make the code visible.
