Set All First Images As Featured

still works

It simply didn't recognize any images in any of the posts, and so didn't work. :(

Didn't see the images in the posts

IT works on 5.0.3

When placing a YouTube or Vimeo video within the first 4000 characters of a post, the thumbnail of that video will automatically be uploaded and set as the featured image for the post as long as the post does not already have a set featured image.
In addition, after setting the video thumbnail as the featured image, an “is_video” post meta field is updated to allow for the use of conditional statements within your loop.

Automatic Featured Images from Videos

Tried this a bunch of times and it doesnt work. No errors or warnings, it just never sets the featured image

No longer works

An essential part of our Wordpress website. Saved hours of work. Thanks very much.

Just cool

If a YouTube or Vimeo video embed exists near the start of a post, we'll automatically set the post's featured image to a thumbnail of the video.
