I am trying to find a way to tap into the "featured image" thumbnail that my custom theme uses for all of my previous posts. I am using a woo theme and they call it a "post image". I have enabled wordpress "featured image" to show up in my post edit page, but I don't want to go through every post I have made in the past and add the "featured image" when I already have a thumbnail associated with every post via the custom "post image".
I know this has had to come up before, but my searching hasn't came up with any answers. Please let me know. Thanks!!
