Preferably tasteful.
(you know, funny signs, ordinary pictures made very funny by a good caption, particularly good gary-larson comics etc…)
I am sure that most of the sites have the same old pictures, and I’ve probably seen them all. But there’s no harm in asking. (is there?)
If comics count then there is the incomparable Calvin and Hobbes site:

Actually it’s been a while since I have been to the site and I hadn’t realized it had a become a pay-site except for a couple of days of cartoons. It used to be free. Oh well.
My bro showed me this…hysterical!
www.collegehumor.com has some funny stuff.
www.fark.com and www.somethingawful.com have photoshop contests that can be hilarious – that’s where I think most of the stuff that’s passed around in e-mail comes from.
That place still cracks me up. Though after browsing some of the DoperPics it may not be humourous to some as it would seem that they should be on that page.

Many plain old funny shots, some nudity, some great “priceless” ads, some cool military type photos.
Just behind Fark and the SDMB on my daily web routine.
