in reply to Hash references and Exif data

Can't help with the EXIF data but I suppose once it's in a format outside its original, it loses the fingerprints.

For the hash reference, you have to create a k/v pair for each key inside of your referenced hash. Dirty. 


    while( my ($k, $v) = each %$image_info ) {
        print "key: $k, value: $v.\n";
    }
