Futallaby (a.k.a Futabally) is software written in PHP to run Futaba-like imageboards. It continues to run on the image board site, 4chan. Essentially it is an English translation of Futaba, the code that runs Futaba Channel.
Futallaby was written by Justin Smith, a.k.a. "thatdog", a Something Awful goon and fan of 2ch.
Futallaby is no longer in development. A similar script still in development is Wakaba, which is written in Perl, and is featured on another image board site, IIchan.
Both scripts are in use at iichan, an English-language site built along the same lines as the Japanese 2chan, and also 4-ch, an English-language discussion BBS.
Wakaba is an image board script very strictly modelled after the Futaba and Futallaby scripts.
It is more loosely modelled after the sort of message board scripts used on 2ch and many other similar sites.

Or links to a good rotation script that works with futallaby would be nice to
the define function is returning true, and the output line in Futallaby is outputting the IMG tag as img src="random.php" as it should, but it still didnt work as it's supposed to (at least sound like it's supposed to).
