The code for the image and link would need to be in HTML for it to work. The code would look something like this:
<a href="http://www.yourLink.com/" target="_blank">
<img src="http://www.YourSite.com/images/logo.jpg" width="200" height="261" border="2" alt="CompanyName Logo!" />
The first part of the link is the href that tells the browser what to do if you click the image. In this case it will send you to http://www.yourLink.com. The image it will show is located at the URL above. You may be able to use it with a local image file as well but I am not postive how you would format the code.
