We have someone that we believe will be attempting to steal our product images that my client took himself, with his own camera, in his own home.

We have been using, on HTML sites (non-cart sites) a javascript for right-click preventing .... and the code goes within the head tags.

Is this something I can do for Zencart or do you think it will break the code of the cart?

This is kind of urgent so any help would be great appreciated.
