A utility script that refinds all image paths for images that have a path whos file dosent exist.

Running this script is usefull for moving projects to new computers and fixing broken image paths.
It works by taking a searchdir and finding all the images in that dir, then using the largest images (if doubles are found) to avoid using thumbnails.

This should be mived from the UV to the image menu when a python slots available.
