I downloaded this plugin on reading your awesome 'WordPress for Photographers' e-book. I even tried using this plugin on an older version of WordPress, definitely pre-3.4. I was trying to get this set up on my staging site with 3.4, and it does not seem to work at all. I tried uploading a file with all the metadata - EXIF and IPTC. It did not seem to extract and populate the data into the taxonomies.
Can you please help?
