You may have noticed that when you export your placemarks with images attached from Avenza Maps as a KML and open that KML in Google Earth, your images have been rotated in some way and now display upside down. Most modern cameras have a rotation sensor which writes an orientation EXIF tag into the file to tell your software how to turn the photo for display. Apple iPhones now exclusively use EXIF orientation tags to ensure images are displayed correctly in the software. Google Earth, however, does not obey these orientation tags and therefore, your images do not display correctly in this software.
In order to get the photos to display correctly in Google Earth, there are a couple of things that you can do. The first is to orient your device correctly when taking the picture so that the photo will display properly in Google Earth. We have had success by rotating the device 90 degrees in a counter-clockwise direction to take a landscape photo. This has displayed accurately in Google Earth every time from both iOS and Android devices.
Another option is to extract the KMZ file using software like WinRar and 7Zip, opening the images folder that is extracted, rotating the images in the folder so that they are now the correct orientation, create a new zipped folder with the .zip extension, drag the KML (called Doc.kml) and the images folder into the zipped folder and then change the .zip folder extension to .kmz.
If you create the zipped folder and cannot see the .zip extension after its name, you will need to change a setting in your computer to be able to edit this to .kmz. To do this, go to the control panel, search in the control panel for 'Folder Options', go to the view tab and then scroll to make sure that 'Hide extensions for known file types' is unchecked. You will then be able to change the extension on the file.
**Please be aware that this doesn't work on Google Earth Pro, but it does work in Google Earth (web version)
For the orientation to be displayed correctly in Google Earth Pro, if you are on Windows, you can download an app from the Microsoft Store for free, JPG Spinner (https://www.microsoft.com/en-ca/p/jpg-spinner/9nblggh3tvgw?activetab=pivot:overviewtab) and that will properly rotate the images to be viewed.
If you also remove the EXIF data from the image the image will also be orientated properly. Keep in mind that will delete the georeferencing for the image. Therefore it is best for you to create a copy of the images first before you remove the EXIF data.
This is only confirmed for Windows OS computers.
