[SOLVED] help with clearing cache

[scarhand]

alright i created an image upload form

 

everything works perfect, except that after a new image is uploaded (to replace the old one), it still shows the old one.

 

i have added this before any html code is output:

 

<?php

header("Cache-control: private, no-cache");
header("Expires: Mon, 26 Jun 1997 05:00:00 GMT");
header("Pragma: no-cache");

?>

 

and that hasnt fixed anything. i can only see the new image if i manually refresh the page.

 

any help?

the only full proof way i have found is to add a random number argument at the end of the get

I store my images in database and call it up with image.php file so for me

I just do

 

<img src="/image.php?imageid=223132&rand=<? echo rand() ?>">
