You'd need to hook into the javascript click event, and log the cookie 
from javascript. However, unless you tie the cookie to some form of 
token/id on the server-side, you should not rely on the presence/value 
of a cookie for anything which needs to be secure.

Again, use javascript to read the value of the cookie, and set the image 
src to whatever image you want.
