Chrome Cast binding

Find this in a a post in google+

The HTML video tag on a ChromeCast device does not support MJPEG, but the image tag does. So all you have to do is point the source attribute of the image tag to the video URL of the server on the smartphone.

Can i do this with the Chromecast binding?

There is an imageSrc channel on the chromecast.
Give it a go and find out!

I thought that was the url of the image (e.g. albumart) connected to what i am playing.
