We can run animated .gif, .jpeg, .swf and rich media artwork. We can also redirect to third-party Java scripts. Artwork must be hosted on our servers. For highly targeted campaigns, such as day-part targeting, geo-targeting, day-of-the-week targeting, etc., please contact us and we will help find a solution for you. Targeting options on popunders are fairly limited; targeting for banners is more robust and is available for added fees for the advertiser.
