Hi, at the moment you have the option to place one banner in the top of the website, a single ad appearing in the single ad page the category page and the search results page. Additionally you have a widget with 125x125 ad space dimensions to place in the sidebar. You can place multiple ads in that widget area in the sidebar. If you need to place more banners you will have to modify the theme's code according to your needs. Please let me know if you need more information.
