i have followed this example from my manual and it worked well.
it displayed the imagejpeg($thumb) nicely.
now i wanted to save this new resized image to a file in my images directory, what command or procedure should i do?
<?php
$filename = 'test.jpg';
$percent = 0.5;
header('Content-type: image/jpeg');
list($width, $height) = getimagesize($filename);
$newwidth = $width * $percent;
$newheight = $height * $percent;
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
imagejpeg($thumb);
?>
