We have had photos in the Global Address List for some time now; they used to be saved in an Active Directory attribute. With Exchange 2013 and higher, we now have the option of using high-resolution photos instead of the traditional 48 x 48 pixels photo that were saved in the thumbnailPhoto attribute in Active Directory.
