I suppose this is a tad bit unnecessary, but I'd like to have different signatures load up, sort of like that thingie where different avatars can load up by using some sort of script I can't remember. I'm sure I can make a webpage that loads a (small) something every time I refresh, but since I can't embed html here, I can't use that method (though FG is another matter...I'll do that for FG)

So what am I left with? If it's not possible, can I at least get a tutorial/information on how to get random images to show up in the signature? (I'm speaking about a script or something that loads a random image based on a list of urls).
