301811 Script to edit graphic

I need a script that will show a graphic on my website based on the visitor's current date. EXAMPLE: Today is 03/22/06 I want my page to display the image named "[login to view URL]". Tomorrow is 03/23/06, so I would want my page to display the image named "[login to view URL]" The script will need to support all days of the year. Jan 01 thru Dec 31 Also, if there is a problem with the date (like leap year) or any other unforseem problems, I'll need the script to default to an image named "[login to view URL]" The page is currently just plain HTML and I'd like to keep it as simple as possible. Nothing complex that could crash a visitor's browser. Open to php or javascript, maybe perl or CGI, but I prefer something simple and easy to manage.
