Anybody kow of free(no registering) image hosts

I want to put images in the forum, I know I can probably use Flickr or Photobucket, but are there any good ones that anyone can reccommend that don’t require sign up.

I tried one I found called but the image doesnt seem to display when I visit the link directly. is used a lot on the “Reddit” forums has been created by the PirateBay guys (so it should be reliable)

Thanks I will check them out. I am too lazy to register with the likes of Flickr
