I have a .kmz file that I can't load properly into QGIS. I already rename the file as .zip and look into the files inside. I found the .kml text file and an other folder with a .png image (the one that I would like to open in QGIS as raster). 
When I open the .png directly in QGIS, the values doesn't make too much sense and I loose the geo-reference coordinates. Any advice on it?
