Go login into your affiliate account then go to Promo Tools page and choose Animated or Static Banners and download the banners you will use and then you have to go to Linking Codes and choose the link you want to promote, I recommend you to use any link from the Program: Revshare list of link codes.
So you have to upload your banner to your website and use it along with your affiliate link, because they do not allow hotlinking for some reason.
Now, if something is still not clear for you, let me know.
