Picture Saving After resize.

[Dan911]

I have created an image resizing script, and am having trouble saving the resized image to the server. 

imagejpeg($image_resized, $imagelocation);

should save the image to where I designate $imagelocation as, but it doesn't.  Should i use fopen instead?  Also, is there any way i can make it so this script scan folders and  apply the script to certian files in them? And why does my script not work when I say open_image($picture); when picture is defined as $picture = 'flower.jpg'

 

Thanks, Dan

 

<?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
$imagelocation = 'resizedflower.jpg'
header('Content-Type: image/jpeg');
imagejpeg($image_resized, $imagelocation);
die();

        # JPEG:
        $im = @imagecreatefromjpeg($file);
        if ($im !== false) { return $im; }

        # Try and load from string:
        $im = @imagecreatefromstring(file_get_contents($file));
        if ($im !== false) { return $im; }
