Hi Guys,
I'm trying to find a function that would look to see if a post has the_post_thumbnail set, and if not, then it would use the first uploaded image as the post thumbnail.
This would make the_post_thumbnail feature backwards compatible for old posts, but more importantly save my users the time required to set the post thumbnail when only one image was used on the post (%90 of all our posts).
Thanks for the help!
