Ok I tried it on incognito.
I opened the front page and opened an image with expando. Took one second.
Came back 15 minutes later and tried to open another and it is still loading after 15 more minutes. I waited for 1 minute of loading before trying another image and it loaded fine, and so did others. I came back 15 minutes later and tried opening one more image and it was fine.
So it looks like the issue is with either the first image or images opened after waiting a while. only initially, and opened only soon after that first wait.
Very convoluted, I almost want to just disregard my post, but here's the info anyways.
