daverj - that's why I said "casual" theft. The majority of users - especially those who steal artwork, who seem mostly retarded - would have no idea about disabling javascript or searching their cache, although I reckon it's possible to code for both these issues if you're really determined (I'm 95% sure you could prevent screen-grabbing, too, if you had time on your hands and didn't mind a very annoying and convoluted display process!) But that aside, in most cases, if they can't right-click or click save on the auto-toolbar they'll go elsewhere.
