How do I geo locate photos from my Iphone to google earth

In Google Earth Pro if you add an image to a placemark or add a photo using the Add - Photo option, and the photo is geolocated you will be asked if you want to move the placemark to that location. If you use this option, the photos would need to be saved to your computer, and you'd have to add them one by one.

You could print the map with the placemarks and labels visible, but only one placemark balloon can be open at one time.

An alternative might be to put the photos in album in Google Photos, and then add them to a My Map. To do this, create a new My Map (https://www.google.com/maps/d/), select Import in the Layers panel, then Albums. Double click the album with your photos to open it, and then select the photos you want to add, and click Insert.

If you add the photos to a My Map you can then save it as a kmz file to open in Google Earth Pro, or open it directly in Google Earth for web.

I suggest you try and then come back if you have specific questions.
