  I wan’t to change the thumbnail attached to the link when I share my blog on facebook. Only three options come up, however, how do I choose image that is not one of the three choices.

  Howdy!

  Facebook will select an image from your post, if one exists, in the following order:

  Featured image
  Image from an included gallery or slideshow
  Image attached to the post

  Since you set a featured image on your post, it should have picked up on that. I was able to reproduce this on your latest post, so I ran it through the Facebook debug tool:
  https://developers.facebook.com/tools/debug

  The tool initially told me the image was too small, even though I could see that it was larger than the 200 x 200 minimum size requirement. So this looks like a Facebook bug.

  Oddly, I ran it through the debugger again, and suddenly it pulled the appropriate image, no warning about the size. Now when I try to share your latest post, I see the post’s featured image instead of the three unrelated default images.

  Let me know if that fixed the problem for you, too.

  Cheers,
