How do people make these sort of dynamic images? There's also that IP image for a forum signature that tends to freak people out and make them think that you know their IP.

Generate them using some kind of software and use CGI to output them as an image.

Use JavaScript...it's very fast and client-side.

Ewww... no. Never use Javascript unless it's something that can't be done without it; and even then, webpages should never rely on it to function. Remember there's actually a decent percentage of people who have Javascript turned off.

Any CGI program with the ability to create images can do this. PHP, for example, provided it has the appropriate extension installed.
