Is it possible to allow users to save images from javascript gallery?

Q: I would like to purchase a VisualLightBox product for private use (for removing the footprint product). Can visitor (my friends and family) download photos from gallery ?
Thank you for your reply.

A: If "Enable right click on image" option is enabled, everyone can right click on your images and select "Save image as..." item in the menu.

You can find "Enable right click on image" option at Gallery->Properties->General tab.
