You can upload image banners that represent your brand.
Your partners will also have access to your banner images within their dashboards. They can grab the embedded HTML code for their website or download the image to share along with their link through social media or email.
As a reference, here are some of the most common image sizes used by our publishers:
320x250 - Medium Rectangle
160x600 - Wide Skyscraper
728x90 - Leaderboard
468x60 - Banner (slightly less popular)
Simply click "create new" and upload your banner. Afterwards you can then change the category (or create a new category) to place the banner in.
Additionally, let us know if you want to add text links. We can help you set that up, upon request!
