Code (markup):

 

do the following

Click - Presentation - sidebar widgets.

Create a textwidget or you should see Text1 already there.

Drag it to the sidebar and then click on the right of it and put your banner there (link, description)

click Save Changes.

you should see your banner there.

Note: if you're using WP-Cache you wont see the banner just jet. hold down Shift and reload the page and it should come up.
