You can add music to your campaing through soundcloud/fanburst etc. Its is very helpful. But for me, images that we can find on your searcher are pretty... weak? It would be wonderful if we could transfer our Pinterest Folders to campaing. Their searcher is perfect has a lot of photos. I don't know how exactly does work transferring this music. Maybe we can have simillar thing with Pinterest.
This is a pretty sweet idea. I find myself using Pinterest just to find and pin maps for later use. Once I get a vote back, I'll come back around to this.
