save your banner as banner.htm or something like that.
under admin area ,click banners,click 'create new banners' ,add that banner....add the banner short code to where you want to show ads (for eg:you may add short code to your e107 theme).Pls refer e107 wiki for the entire details.I think everythin there..or if you can find there pls post back here.
Is that what you mean? If not pls explain what you want to really get.
