I need to add this: <a href="https://www.edrvtracker.com/rd/r.php?sid=195&pub=590070&bid=542&c1=&c2=&c3="><img src="http://ads.edrvtracker.com/rd/b.php?bid=542&sid=195&pub=590070" border="0" width="728" height="90" /></a>
to an image on one of my pages. How can I do that? I am not a programmer and just really need some guidance. Thank you.
