Here's how it goes. Somebody posts the first image they see on a new website, BBC, FOX, Sky, WHATEVER.
Then, the next poster will do a funny comment on it. Like you do when you're looking at a picture man kissing a woman and saying “this tounge tastes horrible”. You know what I mean. And, you know, keep the whole thing clean. A person doesn't have to give a commentary AND an image, they can just leave one or the other.
Example:

“Shouldn't have had that last burrito…”
Okay, shoot!
