The down side is that people are prevented from using other right click functions such as opening a link in a new tab/window which actually keeps them on your site.

Images can be copied in seconds even if you have a no right click script. As a demonstration (with the owners permission) I once "stole" an image from a "protected" page and opened it in a graphics viewer. Opening the image took longer than acquiring it!
