Well, it doesn't take long, but if you have in Zulu Dawn 5 different posts on the same page of 30 pictures each, it takes a little bit.
And as I said, I would suggest putting the spoiler tags at the beginning and end of each of the POSTS, not the pictures. You could put the team that's going, then the spoilers with EVERYTHING inside. That way it's just one set of spoiler tags. It would basically just hide the teams and you could scroll down to whatever turn you had next to read without needing to load all of the previous turns on that page.
Also, for the Unfunny thread, instead of making it a quote box, you could make it a spoiler box, cutting down on those ridiculously long conversations that people post on there.
It's just a way to be able to read through conversations on a thread without having to deal with lengthy blocks of pictures, and all you would have to do is post ONE [spoiler] at the beginning and ONE [/spoiler] at the end.
