Display Geotrust Certificate on Marketpress pages

Hi All,
I have been developing a Marketpress site using Stripe gateway. I purchased a SSL certificate from Geotrust and would like to be able to display the seal on the shopping cart and check out pages. I've tried looking through the code to see where to add the code from Geotrust that calls the certificate but can't seem to find the right spot. Anybody have any ideas? Thanks in advance.
