The more modern tools recommended by the Microsoft engineer above are just not as simple or as functional.
There's a good description of how to install Microsoft Picture Manager at http://www.askvg.com/how-to-install-and-get-microsoft-office-picture-manager-back-in-office-2013/
I suspected it might not work with Windows 10, but it did.
I used the version included in Microsoft Office SharePoint Designer 2010, which is a free download from Microsoft
(the 2013 version does not include Picture Manager).
