I was wondering how I go about changing the Logos shown on the Checkout Page for Paypal.

The images are exactly alike

[scr]https://www.paypal.com/en_US/i/logo/PayPal_mark_37x23.gif[/scr][FONT=Arial, Verdana] Checkout with PayPal. The safer, easier way to pay.[/FONT]

[scr]https://www.paypal.com/en_US/i/logo/PayPal_mark_37x23.gif[/scr]Save time. Check out securely.
Pay without sharing your financial information.

The first is for Paypal Express Checkout and the Second is for the Paypal IPN - Websites Payment Standard.

I would like to make them so that customers see a difference.

I am using ZenCart version 1.3.8

Thank you for any help you can give me in advance.
