The hated hashtag. Well sort of- so I am getting married here in a couple days and my fiancé has given our wedding a hashtag, well why not!? So quick couple clicks and I had an updating slideshow on our AppleTV in our family room.
I started with this IFTTT script, and with Google Drive app running on my mac, I set my Home Sharing photos to be that specific Google Drive folder. Easy peasy. So then on the AppleTV you can select photos from Home Sharing and boom. You’re all set.
I am sure there is an iCloud way to do this lurking somewhere. Maybe a folder action to import into iPhoto and send to iCloud? Hmm maybe another time.
