I've got an InDesign doc ready for to send over to someone. Along with it I've got an images folder full of placed images that the InDesign file references.
While I was making my document lots of images went into this image file, but now it's gone through several iterations and not all of them are still needed/in use.
To keep things simple when I send over this file I only want to send over the images that are actually used. Is there a simple way to get InDesign to export a copy of all its linked files into a 'master' folder?
