It depends on what you're protecting. How and if the images are generated, etc. If they are pulled from PHP or other generated pages that display the images, then you can use the referrer in that aspect. However, that won't stop them from linking directly to them, based on the referrer, if it doesn't filter through something to do the checking. This is why mod_rewrite is perfect for this as well as many other cool things.
