Kim,
Do you just want the logo on the page or are you looking to add the paypal checkout buttons on your pages? You should be able to go into the html of the page you want and add the snippet of code.
I'm not sure what platform you are on whether it is just a web site or if you actually have the ecommerce platform. Depending on which, there would be a different method of accomplishing what you want.
NetSol has some forums specifically dedicated to implementation questions and product details. Try here - http://forums.networksolutions.com/
Hope that helps!
