Importing Images Into SharePoint User Profiles My Sites

To make the user images that we have uploaded into the thumbnail Photo attribute in Active Directory available in SharePoint we will first need to map it to the Picture property in the User Profile Service Application.

1. Firstly you will need to go into the User Profile Service Application.Central Admin > Application Management > Service Applications > Manage Service Applications > User Profile Service Application.
2. Then you will need to go into the Manage User Properties section and edit the Picture property. 
3. Next we will map the Active Directory property thumbnail Photo to the Picture property in SharePoint.
4. Once the mapping has been applied the Manage User Properties page will look like this.
5. Now we will need to run a Full User Profile Synchronization job so that SharePoint can import the user images from Active Directory Synchronization > Start Profile Synchronization > Start Full Synchronization.
6. Lastly we will need to force SharePoint to update the User Profile Database - This will create the thumbnails that are used in My Sites and the User Profile Service. This will need to be run in the SharePoint PowerShell Console with the appropriate My Site permissions.
