Images are there but not being displayed?


I am getting this strange issue on my site -

Image 1 attached with this message is what the "media" library looks like. See how the images are grayed out! The are actually there online like these -

But everywhere in the dashboard it is greyed out! even when I embed it in post, they won't show up. This is all a bit strange to me.

Please help in resolving the issue...
