Awesome, thanks John. We have about the same number of images to georef so that will be a big help. I looked at the georeferencer code which is how I discovered that some of the properties were stored in QSettings. I'm not too familiar with c++ though, but since the qgis api can be used to do custom applications I was hoping for a constructor for the georeferencer that I could use.
