hi,
i am having difficulties here.
Below is my situation:

i need to periodically refresh a jpeg image in a web page. The jpeg image is stored in a server with apache installed. The jpeg image's source is coming from a live camera connected to the server.

how to write a program in ajax to update the jpeg image every 5 seconds.Given that the jpeg image changes every 5 seconds.

Note: i am using <img> tag and the <img> is located in a <table> with <tr> and <td>.

Can anyone write me a working sample program please. I tried b4 but the jpeg image keeps on flickering.....
Thanks.

In my opinion you don't need AJAX for this. If the image's URL is always the same you can just use setInterval to set it to the real URL but with a spurious querystring to force a refresh. E.g. if the URL is getMyImage.php?id=123 then set it to getMyImage.php?id=123&r=123456 where the r= part is a random number, based on the time perhaps.

I think this is just what I want - in a round about way. I am a complete n00b at Java/ajax tho.

What I have, is a very annoying page with a complicated sign-in that times out after 5 minutes. What I want to do is load it into a frame where Javascript periodically reloads it to refresh the timeout.

Is this possible? Could someone show me a basic example? I'd be ultra-grateful!
