[RESOLVED] GD thumbnail creation help

[AdRock]

I have found a script that resizes an image upon upload which works

What i want to do is as well as create a thumbnail image, i want to create a larger image an dput it in a folder called large

I am having trouble getting the large image to create

Here is the code that works for the thumbnail creation

$im_file_name = 'pics/' . $_FILES['photo']['name']; 
$image_attribs = getimagesize($im_file_name); 
$im_old = imageCreateFromJpeg($im_file_name); 

$th_max_width = 100; 
$th_max_height = 75; 
$ratio = ($width > $height) ? $th_max_width/$image_attribs[0] : $th_max_height/$image_attribs[1]; 
$th_width = $image_attribs[0] * $ratio; 
$th_height = $image_attribs[1] * $ratio; 
$im_new = imagecreatetruecolor($th_width,$th_height); 
imageAntiAlias($im_new,true);

$th_file_name = 'pics/thumbs/' . $_FILES['photo']['name']; 
imageCopyResampled($im_new,$im_old,0,0,0,0,$th_width,$th_height, $image_attribs[0], $image_attribs[1]); 
imageJpeg($im_new,$th_file_name,100);

I want to create an image 400 x 300 if that is possible

On upload the file is stored in a temp folder and you need to use move_uploaded_file to move it to it's final location. Then you can perform your image functions on it.

This is the full script including hte form to upload

<h2>Image Uploads.</h2>

<?php 

//This is the directory where images will be saved 
$target = "pics/"; 
$target = $target . basename( $_FILES['photo']['name']); 
$pic=($_FILES['photo']['name']);
$gallery = stripslashes($_POST['gallery']);
//This gets all the other information from the form 

$pic=($_FILES['photo']['name']); 
if (!isset($_POST['gallery'])) {
?> 
<fieldset>

echo "The file ".basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the gallery ".$gallery; 

should be

echo "The file ".basename( $_FILES['photo']['name']). " has been uploaded, and your information has been added to the gallery ".$gallery; 

and

$ratio = ($width > $height) ? $th_max_width/$image_attribs[0] : $th_max_height/$image_attribs[1]; 

should be

$ratio = ($image_attribs[0] > $image_attribs[1]) ? $th_max_width/$image_attribs[0] : $th_max_height/$image_attribs[1]; 

Just some mis-named variables.

If you set error_reporting to E_ALL you can pick errors like this up as it reports unknown variables

If you do this it will throw errors up for the code before the if clause, moving this to be the first thing in the else clause corrects this.
