header(Content-type: image/jpeg) not working

header(Content-type: image/jpeg) not working



I have written some code to resize an image (followed PHP manual) but I

cannot get the image to display. I know the image data exists as I can see

it when I echo the $thumb but I can't seem to get the actual image to

display.

This is the code I have used:

$row = mysql_fetch_array($result);

$image = $row["image"];

echo $image;

echo $row["name"];

list($width, $height) = getimagesize($image);

$newwidth = $width * 0.1;

$newheight = $height * 0.1;

$thumb = imagecreatetruecolor($newwidth, $newheight);

$source = imagecreatefromjpeg($image);

imagecopyresized($thumb, $source, 0,0,0,0, $newwidth, $newheight, $width,

$height);

header('Content-Length: '.strlen($thumb), true);

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

echo imagejpeg($thumb);

Thank you for any help
