Smileys & Images not working properly?

For some reason, not all of the smileys or images posted are showing to me - is anyone else having the same issue?

I have done a fresh install of Firefox and Waterfox, and I have tried looking at the site using both those, and IE and there is no difference; I have since cleared my cache (not that there would be much if anything in it, but it was worth a shot, and still no joy.

Anyone else missing images (such as our wee friend )
