In the past I've read about an app/plugin that will go through your ID file and resize/resample your images so that they are the size of the image box they are placed into, thereby reducing the overall size of your ID file.
But I cannot for the life of me remember the name, nor find it in the Google. Maybe I'm just tired this morning.
