466084	2006-06-25 23:03:00	Hi all I currently have a dynamically generated page (php) where my client adds pictures as part of an online course, What i want is that when the teacher adds a new image (every 5 - 10 mins or so) for the pupils pages to update, Currently what I have is a meta tag refresh that refreshes the pupils page every 5 minutes now because the page is dynamically generated (shows the 2 most recent images), i think checking it with javascript would create the same sort of server work as the meta tag refresh, So i had the cunning plan that i could use javascript to check the images directory, and when a new image was added it would refresh the page, or even make a "refresh" button appear on the page The images are numbered as they are uploaded so the first image uploaded will be image1 the next would be image2 etc, Now i dont really understand javascript or its abilities, but I thought to tackle this one of 2 ways get the javascript to check the number of items in the images directory (and store it as a variable), when it increases, the page refreshes get the javascript to check the most recent creation date in the images directory (and store it as a variable) and when a newer date appears refresh the page If any one can help i would be exceedingly grateful Cheers Nigel	Morgenmuffel (187)
