Question about facebook

It depends on if the website conforms to certain standards, which FB then uses to populate the little image field. Some websites (when posted into FB) have little arrows under the picture to let you select which one you want to display. Nothing you can do about it apart from that.
 
It's either FB or the website that changed something. I'd lean towards website.

As for what you can do: probably not much. Should you bother?: probably not.

:p
