Mozilla + image rotation

[Wesker99]

Howdy, I just made an image rotation script that should output a random image every time you refresh it. It works fine in IE, but in firefox it works for like the first 3 refreshes, and in Mozilla it only outputs the same image every single time.

I find that if you manually put the the url of the image into you're browser, it'll work every time, but if you have it in a page, and you press refresh it does what I have stated above..

Assuming this isn't a problem with my luck, is there anything I can do to get around this?

Here's the code:

<?
function ImageArray($directory) {

$handle = opendir($directory)

$imageArray = array()

/*Opens $handle*/
while (false !== ($file = readdir($handle))) {

if ($file != "." && $file != "..") {

/*If the file is .png then it goes into the array*/
if(ereg(".png$",$file)) {

array_push($imageArray, $directory."/".$file)

}

}

}

closedir($handle)

sort($imageArray)

return $imageArray;

}

$images = array()

$images = ImageArray("./sigs/wesk99")

shuffle($images)

Header("Location: ".$images[0])
?>

I've been looking at this for hours and I can't think of anything. Some new eyes might be able to find somthing I've overlooked. Any help would be greatly appreciated.

Thanks a lot smile

Works for me, but then again I'm using IE6 SP1.

EDIT: Didn't work at all when tested under Firefox 1.0, not even the first three times.

Try using some or all of

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT" wink ;
header("Last-Modified: " . gmdate("D, d M Y H:i:s" wink . " GMT" wink ;
header("Cache-Control: no-store, no-cache, must-revalidate" wink ;
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache" wink ;

I tried header("Cache-Control: no-store, no-cache, must-revalidate" wink ;

But I havnt tried the rest, thanks.

It seemed to work for like 5 refreshes then it went back to the same old same old. sweatdrop
