I wrote this modification because I have a client that needed several sidebox banner boxes and did not want the information in the sidebox to rotate.  I wanted her to be able to switch out pictures / advertisements if she needed to down the line.

What this mod does is allows you to have an additional sidebox banner box that will look like the rest of your sideboxes on your website and can be controlled in your Banner Manager section so you can see clicks, hits, etc.
