USAGE

You must have a document open.
This script checks if the document contains image frames with a broken link.
If any is found, it will ask if you want to look for the correct image and then
prompt for the new location of the first image.
It will then check all other image frames with a broken link, and look for an image
of the same name in the new location. It the image is there, the link will be
replaced.

You would be wise to work on a copy of the original to avoid accidentally include
the wrong images.
