Frequency of image change increases with every connected client #48

Issue: When only a single client (browser) is connected to the MagicMirror, everything works fine. But open another tab with the MagicMirror Url and the images change in higher frequency in all tabs. Open a few more and the background image changes like crazy.

Config: Default installation with default settings, only changed transitionImages to false so the image change is visible with high frequency.

I'm seeing this same behavior. I have 3 tablets in the house all looking at a central server-only MagicMirror instance and the images just flash like crazy on each tablet.

I see the same issue, is there any way to avoid this?

The issue seems to arise because the timer is instantiated once on every client (by MMM-BackgroundSlideshow.js) , as opposed to just once (if it were to live in node_helper.js) - and when any timer fires the image changes.
