Thread: Embeded YouTube displays but not the image inside the border.

Back to this.
If I insert a full watch?v=ZCOSPtyZAPA type URL into a post my Chrome based browser doesn't show the preview image and the video title.

If however I paste in this as a [VIDEO =youtu.be/ZCOSPtyZAPA/VIDEO] " it shows the preview picture and the title.

This is the same for all forum users who insert youtube videos into the their threads. So the short form URL works for my browser not the long form version.

In the thread old school rock as an example I can see the King Crimson preview and title picture and The Cult which i just added but the rest show only a blank square with the URL address at the top.

It must be a browser setting but which one?
