No pictures! I think I know why.
They suppressed the images because they needed time to get into their personal bunkers before the pant-cr*pping terror hits home and the asteroid-induced riots begin.
But if you need a mental image in the meantime: just imagine a freeze-frame picture of a 100 mile-wide shotgun being fired at your head: that may help :0)
Here's a nice little animation:
It shows the five inner planets, together with the sea of asteroids they're moving through. The yellow dots are Earth crossing asteroids. The blue dots are asteroids that don't cross Earth's orbit. The Sun is at the center, of course, and the Earth is the third large orbiting dot out from the center. We're zipping around through some fairly congested space.
