Preventing a right click download is a fools 
errand. The fact that you are viewing the image 
means that it is already on you computers 
harddrive in the browser's cache. You just have 
to browse it to find the image. Correct 
information is better than false security. I 
prefer "Keys Little Cel Gallery" method of 
stamping the image, at least the image thieves 
will have to work for it.
