Copy it into the scripts folder from GIMP, you will find it then under Filters -> Light and Shadow -> White Balance Puzzle.

I use it more as an analysis tool for existing images. You can detect edits in low contrast areas with this script.
This is an Exif Viewer, mainly for jpeg photos taken with a digital camera. It is an update of the "Exif Browser" plugin from the old registry. It requires a recent version of libexif (tested with 0.6.16).
Instructions for Linux:
You need to have gimp already installed on your system. After downloading the file exif-browser.tar.gz, do the following steps.
Save all layers as TGA files, discarding alpha channels and applying layer masks as alpha if they exist. Name becomes imagename-layername.tga
