This is exif data that is stored in the image.
in the language file there is a section:
$lang_exif_info = array("Kameramodel" => "model", "Exif Datum" => "DateTime", "Brennweite" =>
"focalLength", "Blende" => "fnumber", " Belichtungszeit" => "exposureTime", "ISO" => "isoEquiv");
where e.g. model is the key in the exif.
you could e.g. use your own descriptions there and add exif data with an external tool.
e.g.
"Media" => "media"
only the stuff that is in the array above is displayed! therefore you can configure it how you like!

are some editors - I haven't tried one of there - if you do - tell me which one you liked best.
I think xnview can edit exif data too!
