OK, I should have explained the "relatively intuitive" format of
master_iconmap.xml (since it's not completely intuitive).

In the file, WKMG is configured with two elements:

    <callsigntonetwork>
        <callsign>wkmg</callsign>
        <network>LyngSat-tv/ww/wkmg_orlando</network>
    </callsigntonetwork>

and

    <networktourl>
        <network>LyngSat-tv/ww/wkmg_orlando</network>
        <url>[LyngSat]/tv/ww/wkmg_orlando.jpg</url>
    </networktourl>

based on the fact that the URI for the WKMG logo exists at:

http://www.lyngsat-logo.com/logo/tv/ww/wkmg_orlando.jpg

The <network> simply has to be unique in the file and must match for the
<callsigntonetwork> and <networktourl> elements (so using a format as
derived from the URI will ensure uniqueness without having to search
through the file).

Note, also, that lyngsat-logo now offers a hi-res version at:

http://www.lyngsat-logo.com/hires/ww/wkmg_orlando.png

so, by changing the "/tv/" to "/hires/" in the <url> element of the
<networktourl> element, you can get hi-res versions of your icons.
