Some Pictures in Facebook albums are blank in the Gallery app Galaxy S4

[AC Question]

Looking through the pictures in the Gallery app most of the Facebook pictures are blank. I have over 20 albums and in most of them most of the pictures are missing For example I might have one or to picture out of six. . When you click on the empty photo it say Unable to load photo. A couple of them you click on the photo and it appears. Some of them the picture is there on the side but where the albums are but when you open the album it is empty.I really don't know when this change happened. i was always able to see all of my Facebook albums before. I have a Galaxy S4 which is up to date.
I have uninstalled and reinstalled Facebook but nothing changed. I have the Facebook app set to Sync Gallery. I don't know what else to do. I hope somebody can help me.

Thank you
