Secure Emblem?

Hello,

Is there a way to add, either to the gallery or cart, an emblem or check of approval saying that the SmugMug cart is secure so people feel safe? Protected by Smug Mug & a little 411 on how safe it is to purchase perhaps? My client is asking for this. I know I can add an image to the custom code I am using for the gallery, but not sure if there is a graphic and link that I can add? Would the check mark emblem on this page (http://www.smugmug.com/help/payment.mg) make sense if I added it to the gallery? Is there a page on smugmug that explains to shoppers how secure the cart is?

Thanks,
Steve
