Alright, so I've got my radio show's site up right now. (It's
http://www.billfredinthenighttime.com if you're interested.)
I'm trying to come up with a way to send up an alert (displaying an image) that I'm on the air at that time without having to dive into the HTML. My host supports PHP (in fact, that's how I got the nifty random image at the top going), but I honestly don't know a thing about it.
So, can someone point me to a way to do that? Or even better, point me to a way to learn to do that?
