[FF] XFMG: Rebuild EXIF Data 1.0.0

Simple add-on that adds a cli command to rebuild the EXIF data for all the JPEGs in the media gallery.



This is useful if used after an import from another gallery system, as the current importer (well, PhotoPost at least) doesn't pull in any EXIF info.



Use it from the command line: php cmd.php xf-rebuild:ff-er-rebuild
