Third party tools
combineppm is very handy when it comes to stitching rendered slices together:

httpovjob is a perl script by Ryan Voots:

Where can the author be found?
Most likely via e-mail, at sam@home.se. (That's right; I don't even try to obfuscate that address, as it already is swamped with spam. Including the word 'httpov' in the subject line improves your chances of being seen. At least until the spammers find out.)
