This page uses a transparent image to cover the picture so that when you right click to save the image you can can only save the overlying spaceball.gif which is a transparent.gif. To use this on other images insert the code or image, then in Dreamweaver click on the top right square handle over the picture (blue) to move the layer and drag the edges to resize it overtop of your photo. The technique does not prevent someone from capturing the image using a screen dump - nothing can stop that - code borrowed from Flikr web site.
