if you have image in your post then facebook will show that picture. but if you dont have image in your post that you want to share facebook will pick the blog main page image, if you have alot of pictures in the post then when you paste the link in facebook and wait a second then you can change your image by clicking next in the edited post in facebook.

 

but nothing happen facebook pickup photos from header social icons

 

then i think you need to check your picture size. facebook dont picture little size pictures.

 

My picture size is more than 100kb

 

Try to paste the link of your post instead of clicking on share button that you want to share on facebook. While pasting link facebook interface show next and previous button that will change images and you will select your desired images on that point. I think in this way you your problem will be solved
