So i read a couple of tutorials and created an image resizing script. However, instead of the image being displayed, i get a bunch of garboly gook. I know this is supposed to be solved by adding
header ('Content-Type: image/jpeg');
but this did not work for me. Can someone please help me?
<?php
//dan's lame image resizer
// Load image
$image = open_image('flower.jpg');
if ($image === false) { die ('Unable to open image'); }
// Get original width and height
$width = imagesx($image);
$height = imagesy($image);
echo 'Height: ' . imagesy($image) . ' pixels';
echo 'Width: ' . imagesx($image) . ' pixels';
// Set a new width, and calculate new height
$new_width = 200;
$new_height = $height * ($new_width/$width);
// Resample
$image_resized = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($image_resized, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
// Display resized image
header('Content-Type: image/jpeg');
imagejpeg($image_resized);
die();
function open_image ($file) {
# JPEG:
$im = @imagecreatefromjpeg($file);
if ($im !== false) { return $im; }
# GIF:
$im = @imagecreatefromgif($file);
if ($im !== false) { return $im; }
# PNG:
$im = @imagecreatefrompng($file);
if ($im !== false) { return $im; }
# GD File:
$im = @imagecreatefromgd($file);
if ($im !== false) { return $im; }
# GD2 File:
$im = @imagecreatefromgd2($file);
if ($im !== false) { return $im; }
# WBMP:
$im = @imagecreatefromwbmp($file);
if ($im !== false) { return $im; }
# XBM:
$im = @imagecreatefromxbm($file);
if ($im !== false) { return $im; }
# XPM:
$im = @imagecreatefromxpm($file);
if ($im !== false) { return $im; }
# Try and load from string:
$im = @imagecreatefromstring(file_get_contents($file));
if ($im !== false) { return $im; }
return false;
}
?>
