There are barriers to access you can implement to varying degrees of success, but if my browser can show the image to me, then I've got the image, and what I do with it after that point is beyond your control. Most of the barriers you can implement are crude hacks that will annoy legitimate users more than they are worth. If you want to have the hi-res image unavailable, but the thumbnail is freely available, you pretty much just put the hi-res outside the webtree and authenticate any way you like... Google for "PHP authenticate user" should do the trick on that. -- Some people have a "gift" link here. Know what I want?
