[Option] Display and extract EXIF information from images? [Variable] showexif [Description] 
Enabling this option will cause PhotoPost to use the JHEAD executable (set in your config-inc.php) to extract any EXIF information to be saved and displayed for photos uploaded. For this to work properly you need to have a properly installed JHEAD program which has the proper path set in the config-inc.php
