Photos included in Blog are not showing up on Facebook

Hey there:
This is a recent (say last two three months) development. I used to be able to select any of the images from blog post for inclusion on facebook. Yet of late nothing is grabbed, here is the link to my current post
as you can see i have three images contained within post.
I am using Pilcrow V.1.4, not sure why this is happening – had several clients ask why they could not cop photo from site review to share – you can find me on facebook as Blues411 or chefjimi patricola.
thanks – this is pretty frustrating since it is my business.
many thanks
