Imageboard software

Is there any sort of software available to get your own imageboard. Something like 4chan, or maybe even the danbooru style one.

From http://wikichan.org/index.php/Ninechan:

"Another notable feature about ninechan is the software it uses. Most people consider it to be almost web 2.0 software, as it has many unique features."

ROTFL. Sounds just as bad as Trevor. Why do so many retards attempt to write imageboard software?
