I've been trying a few of the common ones but none seem to support the feature (XnView, FPV, FastStone)

Now I had read this before so had installed XnViewMP but it wasn't there a month or so ago, so lets hope it arrives soon!Yes, there is a free viewer that will be able to show people tags etc. after the next release (later this month). It is called XnViewMP. It displays all kinds of tags. The next release will be writing tags in a few other IPTC fields so that other programs can more easily display the tags. Note - the new tags will show up in Windows Explorer also.
In a future version of TTP, we will be adding a slide-show sharing service. This will allow you to create a slide-show from a set of pics, upload to the cloud, and share a link with friends and family. The slide-show will show the people tags. This slide-show link will expire after 90 days for privacy reasons.
