We've run a bunch of ads on DFP for our sites, so the AdOps team has those units available for me to reference. In each case, they have a single folder with one HTML file, and then the images that the units are using. They load the html file into DFP along with the images, and then they launch that, I believe.
They have been balking about the various .js files in the folder that I've delivered to them for testing (the hype.js files etc). I am trying to continue using Hype, but also generating the files and the structure they're expecting to receive.
