You can provide a link to the Archives as follows: 
<A HREF="http://www.classicalarchives.com><IMG WIDTH=120 HEIGHT=170 BORDER=0 SRC="path_to_gif/cma_thanks.gif" ALT="Classical Music Archives Recognized Contributor"></A> 
(You'll need to replace path_to_gif in the IMG's SRC= argument with the actual location of the image.)
