This is sort of a strange question, but here is what I am looking for:
I am designing a site for a radio show, I think it would be cool if I could get an image that says "on air" to display only when the host is on air (10-11, saturdays). Ideally, I would have a normal image with "on air" muted out all the time, except for when the show is on. Anyone have any idea how I might achieve this? Thanks in advance,
