I wanted to add logo of credit card next to PayPal Express Checkout buttons on the shopping cart page. I have created a new image combining the standard PP express checkout and some small cc images. Can't find the correct php file to modify to call this new image hosted on my server rather then the PP image hosted on paypal server. If this is somehow violation of PP terms then please advise. If it is violation then how can I just place the cc img next to the pp button?

I read another forum post but it was referring to file that does exist but not being read ... trial and error method is failing me.

the /store/includes/languages/english/modules/payment/paypal.php line 19 definition is not working? Must be another file? I'm new to ZenCart. Actually, the option of accessing PayPal "larger" image is fine too ... just I can't change this if I can't find the right PHP file.
