PHP: imagejpeg - Manual

Any of the functions, imagejpeg, imagepng, imagegif et al will output a direct stream if the second argument is null.

so all i need to do at the end of the script is imagegif()???

imagegif($dimg) (according to your source) will output a direct stream. When you include $filename it copies it to that location. The link in my previous post goes to the manual page that explains it in further detail if you'd like.
-m

Why is that when I call this script from http://localhost:{port}/test.php it comes up. But when I create an html file, and call the script <img src=test.php/>

It comes back w/ and empty image box??

<?php
ob_start();
$filename = "http://images.wsdot.wa.gov/nwflow/flowmaps/sysvert.gif";
$newwidth = (isset($_GET['width'])) ? $_GET['width'] : "538";
$format='image/gif';
if($format!='')
{
list($width, $height) = getimagesize($filename);
$newheight=$height*$newwidth/$width;
switch($format)
{
case 'image/gif';
$source = imagecreatefromgif($filename);
break;
}
$dimg = imagecreatetruecolor(640,538);
imagealphablending($dimg, false);
$source = imagecreatefromgif("$filename");
imagecopyresized($dimg, $source, 0,0,0,438, $newwidth, $newheight, $width, $height);
$filename="$output_dir/test1.gif";
ob_end_clean();
header('Content-Type: image/gif');
imagegif($dimg);
imagedestroy($dimg);
}
?>

Works for me, and I didn't modify it at all, just copy and pasted your code right into a test file.

Now that you know it works then i would recommend you to ident your code, that means:

PHP Code:


			
<?php
if ($this == true) {
    echo('This functions indented!');
} else {
    echo('This one to!');
    if ($that == false) {
        echo('Another level of indenting');
    } else {
        echo('And another');
    }
}
?>
