High resolution credit card logos

Some of our merchants have asked for high resolution credit card logos.  I have not been able to access the logos from Visa, MasterCard, Discover, or American Express, however I did find this useful link from http://www.kpao.org/ which provides downloadable logos.  Thanks to the fellow blogger. See link below. Enjoy.
