simple question - want to add VISA & MC only image

I searched through the add ons but didnt find anything matching exactly what I need. What I want to do is create a VISA & Mastercard only image and place it under all the sideboxes on the left side of all pages. My sideboxes are the same throughout the entire site so a static image would be sufficient as well. Any ideas on addons or how to accomplish this simple task??

thanks

Get images from MC and Visa
admin > config > Credit Cards > enable them and you will see the place holdder images - - checkproperties of image for where it is and name
Make your image the same

Can also add as an src= statement to most any box or a special box
Use the blank sidebox module

i suppose if I had looked at the bottom of Credit Cards I would have saw "Credit Card Enabled - Show on Payment" and put 2 and 2 together ;) THanks for pointing me in the right direction. I modified the images and uploaded them and all is as I need it. Thanks again!
