If you have a graphics program such as Photoshop or Paint Shop Pro all you really need to do is save a separate version of the image that is much smaller. Even if you don't have a graphics program, if you have AOL you can edit it by opening it in AOL and changing the size. Otherwise, your visitors have to wait for every image to load. That's no fun. A step above making them load, but below thumbnails, would be text links to them. Be sure you give them accurate titles, and you will have happier visitors.
