If you notice images in forum threads are missing, the reason is likely to be, because imgur.com has gone and changed the URL on them.

This is mostly with older images, newer images had the correct URLs when you copied the link over.

To fix you just need to add an s after the http in the link.

I have already updated my Postcard Thread, and my images in screenshots thread. Others will have to take care of their own posts, of course. I've probably missed some of my images in odd threads but likely no one will be looking at them so no one will notice. Probably not a big concern for most people, I for one was freaked out when the Postcard Thread was empty
