Default Facebook Scrape Information Posting Incorrect Photos, Freezing Facebook Up

In the past week, when posting a link from my Homestead sites to Facebook, Facebook may display the intended photo to be included with the share, but upon posting, Facebook posts a different photo -- one housed on the page but not the one shown in the preview.  Also in the past week, when posting a link from Homestead to Facebook and then attempting to change the picture, Facebook freezes up.

It seems this is only happening with my Homestead sites.  Other sites preview and publish the same photo.

Any idea?  Anybody else experiencing this?
