Go PRO! A premium version of the plugin has been launched with many more features – See for details
Auto post thumbnail is a plugin to generate post thumbnail from first image in post or any custom post type. If the first image doesn’t work it will automatically search for the next one and so on until the post thumbnail is inserted.
If the post thumbnail is already present, the plugin will do nothing.
If you don’t want a post thumbnail for some post with images, just add a custom field skip_post_thumb to the post and the plugin will restrain itself from generating post thumbnail.
The plugin also provides a Batch Processing capability to generate post thumbnails for already published posts. A new menu item Gen. Post Thumbnails will get added under Tools menu after this plugin is installed.

Plugin interface is very simple and easy to configure. I had issues running it on a large site, but the support for the Pro version is incredible. Tarique went out of his way to help me get everything functioning properly, and I was able to generate featured images for all of the old posts required.
Very straightforward plugin that did exactly what it says on the box: it set the featured image to every first image in the posts.
I needed this for a thumbnail grid of my posts, so this saved me a lot of time.
