Did you change your video’s default cover image on Youtube, only to find that Facebook keeps showing the old image? That’s because Facebook caches the old image from your video. You have to force it to look at the new image.
Here’s how to fix that.
If you’re posting the video in a new Facebook post, follow these instructions. If you’re trying to update the default image in a Facebook video post that was already posted, scroll down to Part 2.
1. Navigate to https://developers.facebook.com/tools/debug. This is the Facebook Developer Debugging Tool.
2. Paste your video URL into the address bar on the page, as shown.
3. Click the blue “Debug” button to the right of the address bar.
4. Scroll down and click the “Scrape Again” button.
Your video preview on the debugger page will now show your new preview image. That means the video is ready to be posted.
5. Post your video URL in the Facebook status message box. It will show up with the new image.
If you’re trying to update the default image on a Youtube video that’s already been posted to Facebook, follow these instructions instead:
1. Navigate to your Facebook post with the video.
2. Click through the date/time link just below your name (or your page name), as shown below. This will take you to the post’s individual page.
3. Now, click the three dots in the upper right corner of the post.
4. From the resulting drop-down menu, select “Refresh Share Attachment”.
Ta-da! Your Facebook video post now reflects the newest default image set on your Youtube video.
