The main scope of the WebAdverts system on my site is maintaining "banner exchange" between my site and others (members). Banners can be displayed on pages via JavaScript, IFRAME, IMG or SSI tags. WebAdverts keeps track of exposures and click-thrus for each banner, as well as of the average total number of exposures per day. Individual passwords allow each of mine advertisers to view their own advert stats (overall and daily) without viewing anyone else's.
Just register yourself as member to "WebStaneA Advertisers" , put the code on your page and after approval the game begins. The size of banners is defined to 468 pixels width and 60 pixels height and they reside on owner's site!
