(oh sick, there's auto-resize now)
the latest forum update made it auto resize to 1000 or something,
Click cause auto resize makes it small.
Oh yeah, in your absence, the forums got a new feature to stop page stretching images, when posting images wider than 1000 pixels, it'll resize the image's width to 1000 automatically, so that's pretty dandy
I used Stylish briefly then got annoyed by the forums briefly flickering while loading.
