    Here is a bit of code to help those trying to automate the specifying of images to be shown when being linked to by Facebook.
    The logic is
    1. If there's a featured image, get the url of the thumbnail.
    2. If not, get the url of the thumbnail of the first image in the post (by attachment relationship, meaning it has to be uploaded while editing that post.
    3. If still nothing, get a specified image from the theme directory.
    This creates a function to place in your functions.php file.

    Oops... here is the code http://pastebin.com/F5JQr2cn

    And yes, there are plugins for this, but I appreciate having snippets like this for template development enabling rapid deployment of sites not dependent upon certain plugins.
