As long you want the images to be visible in a web browser, they will be downloadable.

There is client side scripting that will protect web page images from being saved. I don't know what it is at the moment, but I will research and find it upon request.

Still, the image is downloaded to cache in the browser, and is fully able to be extracted, or a screen shot taken... if you don't want the image to be copyable, don't serve it via the browser. There is no way, absolutely no way you can serve and image, and hope that it won't be saved/downloaded. You should probably consider an alternate solution to the real problem. Perhaps copyrighting your image or placing "watermark" data in it.

HTTrack is even better for offline storage http://www.httrack.com/
Software like this also fails if your determined enough, or have the right tool http://www.share2s.com/protect.html but against the casual person it may do the job...

rich is right. If you server the image to a web browser and the user is knowledgeable and determined, there is not way to protect it. The client side scripts are simply a deterrant to the casual user.
