These headers only works with include, css, js, html, etc. But doesn't work with images files
(jpg, gif, etc.)
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
To no cache images you can use a trick:
$var = md5(time());
$picture_name = "picture.jpg?var=".$var;
picture.jpg is the name of the file that you don't want cache.
