For your problem, do you mean the fb image is not showing?
If the fb image is not showing, pls check if can open it with built-in browser 1st,
1.Make sure not in the settings>browsing settings>image quality> text only mode.
2.Make sure the network is stable, if the connection get interrupted,it would cause the problem.
3.Try to change the image quality to low(menu>settings>browsing settings>image quality).Try to clear the data and caches, turn on/off cloud boost and try again.
