How do I cast gallery pictures from Droid Maxx to TV with Chromecast?

[pleiku]

I am able to cast from YouTube to my TV via Chromecast. However I cannot do so from my gallery from the Gallery pictures I take as no casting icon is present. What is the key to casting stills or movies from my gallery as the Droid Maxx has no microHDMI output? Do I use a USB cord from the charging port? Please advise.

Chromecast does not have the ability to cast from your gallery, yet. There's someone trying to bring us this feature. You can follow him here: https://plus.google.com/110558071969009568835/posts
