Generate KMZ file for Google Earth from PNG with bounding lat/long coordinates?

I have a satellite image in PNG format along with the corresponding bounding latitude/longitude coordinates. I am new to this format, but wouldn't a KMZ just be a zip containing the PNG and a KML with the bounding coordinates?

How should I proceed to convert a given PNG to a KMZ file that can be viewed in Google Earth?

I would prefer python code, but any help/language would be appreciated.

Solution

The KMZ file would just be a ZIP file with the KML file as doc.kml and any referenced image.

Example KML for an ground/image overlay:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">
<GroundOverlay>
    <name>25N_94E_24N_93E_JOG_1966</name>
    <Icon>
        <href>25N_94E_24N_93E_JOG_1966.jpg</href>
    </Icon>
    <LatLonBox>
        <north>25</north>
        <east>94</east>
        <south>24</south>
        <west>93</west>
    </LatLonBox>
</GroundOverlay>
</kml>

The above would be in a doc.kml file with a corresponding 25N_94E_24N_93E_JOG_1966.jpg file, both the files being in the same ZIP file with the filename having an extension kmz:
