I need 3 little simple php osc done. 1 ] I own [login to view URL] , I need a simple banner script installed for the top banners. If you know a good one, if not use this. [login to view URL] 2 ] My banners uploaded to my afilliate program dont show the jpg. 3 ] copy entire site and upload it to my other domain in working condition with database. I dont know why but [login to view URL] looks n'ice then [login to view URL] is zoomed in kinda ugly, how do I get both the same?
