Facebook and Instagram Not Showing All Images
If you've seen (or not) images in your news feed that aren't showing up, you're not alone.
It seems that Facebook is experiencing an issue with some pictures coming through. Of course, they're working on it. Full story.
But if you're just adamant about seeing pictures, you might want to hop over to Instagram for a while. While there, be sure to follow WTUG.
Update: Looks like the issue persists on Instagram, too. Sorry!
