MP3 album covers: more integration with service, more user c

[gernoth]

I like very much that vlc downloads album images from the internet.
However it sometimes misses the right image and displays total garbage.
I am not even aware what service is used to display these images.

So I would like to be able to
* replace an image
* by submitting a better one to that service (if possible and allowed - maybe using the samew standards as wikipedia is appropriate?
* by replacing the local image, pointing to a new url
* get more info on where the images are retrieved from

thanks all in advance!
