How to add or update a photo:
	- 
		Select the person on the tree.
 
	- 
		On the left panel click the "Add photo for [name]" button.  
 
	- 
		Browse for and upload the photo.
 
	These are the same steps that you do to change the photo as well, except that instead of clicking on "add photo for [name]" you click on the current photo on the left.
