Hello, it's been awhile since I came back here... I was trying to figure out how to change a image of some sort every 5 minutes instead of me updating the image myself (which is VERY annoying). I'm doing a meteorological webpage which has a latest updated synoptic chart. I've saved the images with an id like 2009279-0005UTC.jpg , 2009279-0010UTC.jpg , 2009279-0015UTC.jpg up to 2009279-2355UTC.jpg. I have found a simular way in weeks here: http://javascript.internet.com/page-details/week-day-image.html There are probally too many images so it might be best for every 30 minutes instead. Please help -jason
