The Map to KML or Layer to KML tools would be even more useful if there was an option to select the kind of image format (i.e. jpg or png) that would be exported to the KML file.
For example, having some kind of option to select for a .jpg image or .png image within the tool. So if I selected a .jpg image in the tool, a .jpg file would be included in the KML file, instead of a .png.
I know most Garmin, if not all, require the use of .jpg files in the KML file, so that the KML file is read properly in the Garmin (CustomMaps folder).
