RCWeb Random Photo Control

Random Photo Control is the phone-friendly companion to the random-photo viewer. It lets one or more phones cycle through the current Unsplash slideshow, pause and resume auto-advance, and see richer details for the photo currently on the display.

What it does

• Shows a thumbnail of the active photo
• Shows linked photographer and Unsplash attribution
• Shows description, creation date, location, image size, and like count when supplied by the API
• Provides large touch buttons for Prev, Play / Pause, and Next
• Includes a link to the current photo on Unsplash

RCWeb communication

The viewer owns all slideshow state. The control sends commands to the viewer:

rc.sendFunctionCall("random-photo", "randomPhoto.prev");
rc.sendFunctionCall("random-photo", "randomPhoto.next");
rc.sendFunctionCall("random-photo", "randomPhoto.toggle");
rc.sendFunctionCall("random-photo", "randomPhoto.requestState", rc.client);

The viewer sends snapshots back to controls through the global callback:

randomPhotoControl.receiveState(snapshot);

Browser support

Written in ES5 with XMLHttpRequest-compatible state handling, simple flexbox controls, and conservative CSS for older mobile browsers.
