An unexpected side effect was however that the map couldn't be saved by right clicking on it. So I decided I'd write a java applet that could be compiled so that no one could see the original source code. Then I'd use a hidden path that was stored inside the code that nobody could see, and have the applet load the image itself. Easy to place on any web page. You can't right click on it to save it.
Web spiders can see the images.
There are still 3 ways I know to get the images. This is not our average joe programmer either. The other two I can't disclose right now, but you could get most anything using them. Most people won't figure them out though. The swan image at the top of this page is using the java applet.
