What do you guys use to create your banners? I made a few using the 15 day trial here http://www.bannermakerpro.com/ I like it, it's easy to use and am considering buying it. None of my adds are appering though? My CPM is set to $15. Anyone have some tips to share? Could it be that they are note appearing because I made them with the trial version? My text adds are doin ok.
