I wanted to jump in here -- a great place to start is this post: Advertising Banner Production: Start here, where you can learn a bit more about the different tools built into Hype for ad delivery like Advanced Export (great for seeing live feedback on your export file size), Export Scripts, and setting up click tags. A lot of how you test these things depends on the banner network.
