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.
This can happen for two reasons:
#1. 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.
- 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
#2. There’s a server firewall
Your server may be set up to block requests to the Vimeo and Youtube servers as a security measure.
You will need to contact your host and ask them to unblock the following URLs from the server firewall:
