I dont bother at all, sorry but it is mostly is a waste of time. It may spoil the party for casual surfers, but a determined images thief will make short work of it! And they are the very people that need to be stopped; the casual surfer pinching an image for wallpaper is little more than a slight annoyance. Best method is to make your images low res (72dpi) and small (no larger than 700 on the longest side) making them almost useless for print. Or Put a spoiler right across the image (not good) but will stop all but the desperate. ALWAYS put a copyright statement. The sad but true 100% protection method is dont put them on the web if you dont want to risk them being stolen. I can bypass any method of protection quicker than it has taken me to write this. The truth is I dont because I have no intention of using anything that is not my own. For me there is no point. If I see an image I would like to use, I ask simple as that, if I am told no, then it ends there. I can always go and try to emulate it if I so wish.

The Truth is Out There
