Page icons missing when sharing on Facebok

I am trying to share an image on Facebook from my site but when the share window pops up I don't see all the correct image icons. The image I want to share is missing from the icon menu - I can click on the arrow to select another image but the one I want to share is missing.

Any help would be appreciated.

Thanks for your time,
Keith Melder
