images in Facebook publicized posts

    Hi good people!

    My comment is about the way a post appears in Facebook when it has been publicized. It’s nice how the post gets summarized with an image thumbnail. However, I find it annoying that the image that gets put into the thumbnail on FB is the LAST one in my WP post. Really, doesn’t it make more sense to thumbnail the FIRST image from the WP post? It’s not clear to me whether this image choice happens at WP or FB… I’m guessing it’s done before the info gets over to FB. Is there a good reason for using the last image rather than the first one?

    In case it matters, I’m using the beautiful bloggum theme.

    The blog I need help with is



    We have no control over which images Facebook display. All we know has been provided by Staff here:

    • Only the first five images uploaded to a post (direct inclusion/gallery/slideshow) will be sent to Facebook. The images size has to be at least 200 x 200 pixels.
    • To select which image will be used for things like Facebook Publicize, you can use a theme that supports featured images. If a featured image isn’t set or your theme doesn’t use featured images, then the code tries to pick the first image in the post or page. If no image is found, then the blavatar is used.


    Well, according to the above snip, it tries to use the first image in the post. But what I find is that it uses the last image. So I think this is a bug, or the documentation above is wrong.

    I don’t want to feature the image used in the FB summary, I just want it to use the first one in the post the way it says it does in the user docs, as shown above.

    Staff, can we get this fixed or corrected in the doc? Is there a way to make sure a staffer sees this thread?



    Facebook makes frequent changes at their end. This thread has been flagged for Staff attention.



    Actually, Facebook’s criteria for how they select the image tends to change frequently, and they don’t share the details when they do so.

    Overall, we have absolutely no control over what images Facebook chooses (if any).
