imagejpeg() - nothing seams to work

[benjrox]

Hi,
I'm trying to generate a random image using this code:
[code]<?php

$dirname = "/home/www/benjrox.net/subsites/myspace/images/bg/resized/";

if ($handle = opendir($dirname)) {
    while (false !== ($dir = readdir($handle))) {
        if ($dir != "." && $dir != "..") {
            $bgcount++;
              }
    }
    closedir($handle);
} else {
    die("Could not get a directory list");
}

$randimg = rand(1,$bgcount);

$img = "/home/www/benjrox.net/subsites/myspace/images/bg/resized/bg". $randimg .".jpg";

header("Content-type: image/jpeg");

imagejpeg($img,null,100);
imagedestroy($img);

?>[/code]
Except I keep getting this:
[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]<br />
<b>Warning: imagejpeg(): supplied argument is not a valid Image resource in [b]/home/www/benjrox.net/subsites/myspace/images/bg/img.php[/b] on line [b]22[/b]

The images exist, it just doesn't work [img src=\"style_emoticons/[#EMO_DIR#]/huh.gif\" style=\"vertical-align:middle\" emoid=\":huh:\" border=\"0\" alt=\"huh.gif\" /]

Thanks,
Benj

did you create the image resource?


$img = @imagecreate(100, 50)

Ahh, thanks, haha I assumed my original $img was the resource. I only started to learn about the image command yesterday :p
Thanks :)
