I notice that the site selling the images displays them with a PREVIEW icon on them (after you click on one) to prevent you from just save-as'ing the files and copying them to your own phone.  Oh the irony, they steal other's images then worry about users stealing from them. 

I can't even understand why anyone would pay for cell phone wallpaper anyway but.....   FWIW I don't watermark any of my images, I only display 800x600(ish) and I don't think those are much use to anyone aside from looking at on the screen.
