I have generated a KMZ file which contains a few GroundOverlay images (in png). All the images are referenced as relative paths e.g. "files/imageA.png" in the embedded "doc.kml" KML document.
When I opened in Google Earth on my computer, the images were shown as red cross.
Any idea why this occurred? Could it be something configurable in Google Earth to prevent images being shown in the application?
Thanks!
