Google Chromecast supports Google play and Youtube, but unfortunately it doesn’t support casting photos/ videos in your iPhone/ iPad/ Android phones with Chromecast. Good news is there are many good apps from other developers which you can use to do the job.
Here we will look at CastOnTV which has both Android and iOS version, and you can use it to cast photos/ music/ videos in your iOS/ Android devices to big screen TV only with you putting the device and chromecast under the same wifi network.
The iOS version of CastOnTV is free, so you can cast your iPhone/ iPad photos with background music in slideshow way on TV with ease. The interface is also very simple, only tap on the “Photo” and “Music” button to select the files you want to play, then select the Chromecast device to cast them.
