I am trying to read images that are being stored and deleted periodically on one of the directories on my server. What I want to do is create a slideshow of these images. This would be easy using javascript, but since  I don't  know how many images to work with, and since the images are on my server, that makes it a bit harder. I tried doing this via server side code already, but encountered a few problems.. See below link. Anyway, I know javascript can't access my server file, but can Ajax? If so.. can you provide a source or example where I can get started?

Thanks in advance.

my server side code attempt.. close.. but not quite there...

Hi LeeHenry,

Yes, AJAX can do this.  AJAX in a simplistic description allows communication between server-side and client-side scripts.  I don't use ASP.NET, so I can't explain how to do it using ASP.Net, but using classic ASP you would have two pages.  An HTML page that would display the images.  There would be a javascript function making an AJAX call to determine the next image to show.  The AJAX function would get the results of an ASP page that would use the File System Object (FSO) to read the directory of the folder where your images are stored and send the url path to the file back to the javascript function.  

The javascript function would probably have to send back to the ASP page an index number of the image it is currently displaying so that the ASP page would know which image needed to be displayed next.

Hope this helps,
Neal.
