Currently there's very little information about media filetypes
like images, or videos available in the file property panel.

It would be nice to have extended informations like you have with
MP3s: For pictures EXIF data and resolution would make a great addition.

Additionaly, the possibility to click one of these properties (i.e. Camera Used
for images or Artist for MP3s) to filter/search for additional content
in the folder would come in handy.
