I set up a site and after 200 posts wanted to use featured image

I decided not to bother with featured images in WordPress, preferring the text-only listings on my blog posts page. 200 posts later, and I now want to have a thumbnail show against the posts lists, which, of course, I can’t do easily as I used individually named images on each separate post page!

After going through 20 posts and swapping my image to a featured image and changing the format of the post listing page to show a featured image thumbnail i was completely fed up with the process and wondered if i could use a generic featured image for the old posts!

This plug in is magic and now i don’t have to go through the old posts!!!!!!
