Allow for album covers to be retrieved from webserver in lan

Created by: rhoeden

I'm using an nginx instance in conjunction with mpd to serve high quality (1500x1500) album covers in my lan. Previously I used mpdroid that has this function built-in and I was hoping this could be something worth implementing.

$ cat mpd-covers.conf

server {
    listen 80;
    server_name 10.0.0.110;

    location / {
        root /media/music;
        rewrite /(.*) /$1 break;
        try_files $uri $uri /.no-cover-art.jpg;
        allow   10.0.0.0/24;
        deny    all;
    }
}
