When you add a YouTube or Vimeo slide to a slideshow, MetaSlider automatically downloads a thumbnail for the video directly from the YouTube or Vimeo servers.
In some cases, this process fails and your slideshow will display a broken image in place of the Video thumbnail. The video will still play, but the thumbnail will not display.
The Video is Set to Private on Vimeo.com
This stops MetaSlider from being able to retrieve a thumbnail for the video from the Vimeo servers. Here’s the solution:
- Remove the video from the slideshow
- Set the video to ‘public’ on Vimeo
- Add the video slide back into the slideshow
- Set the video back to ‘private’ on Vimeo
