This may not be the most graceful way to do this, since nobody replied to my questions, I had to figure it out for myself, so here is how I made it worked.
Log in your paypal account
Go to the developper’s section (usually on the bottom menu),
http://www.paypal.com/cgi-bin/webscr?cmd=xpt/general/OnlineLogoCenter-outside
Choose the “solution graphics” that you want to insert on your site,
Copy and paste the entire HTML code for that graphics. (Highlight entire text, right-click and then copy).
Decide where on your site you want to insert the PayPal Logo you just copied.
Insert the code you have copied from Paypal at the location in your site you like it to appear. (i.e. in the head.tpl) by right clicking and pasting it in the appropriate location. Only you know where you want it on your site.
In my case I put it in the /skin1/customer/cc_cards.tpl of the package I had purchase from 7dana. I put it on the top of the existing code for cards.gif
Hope this help.
