I don't know if this is possible for something on E, Vek, but on another huge forum that I'm on the admin just came out with a new spoiler feature.
There's just a button inside the post that says spoiler, and in order to see the content of the post you click the spoiler button and it opens up the content.
People have found tons of uses for them, such as in our "Funny Pictures Thread" for people who want to post TONS of pictures at once, it keeps the page relatively small because all you see is "spoiler" unless you want to open the spoiler in which case all the pictures load, then if you want to see something else you can just close that spoiler box by hitting spoiler again and open another one.
People have also been using it to collapse extra large images. That way they can display them in full size but, because it's in a spoiler box, it's not stretching the page because it doesn't open unless you want it to.
I've got a pretty top-rate computer so loading pages in the F&S forum isn't trouble but it's a little daunting when I open a page and suddenly the scroll bar is about as tall as a hyphen is wide and there're hundreds of pictures on a page and I try to scroll down and it's like an endless page of endlessness. Maybe it might help with the page load for some people if they could do something like the spoiler box, I don't know...
Just a thought.
