How to share geolocation tags in photo streams? I have made over 3000 pictures during my last trip, mostly with the iPhone. 

I then shared them as a photo album in iCloud with my family, but neither of us can figure out how to enable geolocation data. It obviously would be quite handy to know which picture is taken where, and display the map like photos can for unshared pictures.

How is that done?
Under Preferences, select "Include location information for published items". You then probably need to delete and re-create your shared album to get the location metadata
