We are using Tridion 2013sp1. And DD4T at content delivery. Our binaries are published to cdn server. Each publication target will publish binaries to different cdn server. Hence, we are unable to resolve image paths automatically for different environments in our web application using DD4T as image path is resolved with path mentioned in publication metadata "image path".
Now, I'm looking for a way to change publication metadata dynamically while publishing from Tridion according to publication target.
