Sometimes you can find photos on Google Maps that are incorrectly rotated. This is one of the reasons you regularly should review your photo contributions. This issue is very easy to spot.

Find Google's official statement about rotated photos here: Photo Rule #14 (scroll down and click on 14: Always right rotation).

It might not be your fault!

A few mobile phones stores orientation data incorrectly in the image files. This can cause Google Maps to show your photos incorrectly rotated even though they look perfect on your phone. You can read more about this here.

If you experience this problem, you can fix the orientation by saving the image in Google Photos.
