To select a different template for your ad you need to select the ad spot you wish to modify, then click Choose Template.
A new window will open and you will see the options for the templates. You can first choose between Banners+ and Pop-Unders/Sliders ads.
Banners+ is effectively the normal template, along with the option for all our additional ad types (pop-unders, sliders etc). Pop-Unders/Sliders is for those who don't want to show a normal banner ad on their site.
Please note that we do not allow custom sized banners, this is because our advertisers supply their own images, and they are designed to fit the templates, custom sized banners would interfere with this.
