I have this function:

```php

<?php
$new_width=100; //Image width Change if needed 
$new_height=100; //Image height Change if needed 

$source_path="../random/images"; //Source File path 
$destination_path="../random/thumbs";
function thumb_jpg($file) 
{ 
    global $source_path; 
    global $destination_path; 

    global $new_width; 
    global $new_height; 

    $destimg=ImageCreate($new_width,$new_height) or die("Problem In Creating image"); 

    $srcimg=ImageCreateFromJPEG($source_path.$image_name) or die("Problem In opening Source Image"); 

    ImageCopyResized($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg)) or die("Problem In resizing"); 

    ImageJPEG($destimg,$destination_path.$image_name) or die("Problem In saving"); 
}
?>

```

That creates a thumbnail of an image uploaded from a form.

I get the following errors however:

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg: JPEG library reports unrecoverable error: in /home/arctichosts/public\_html/admin/admin\_uploadrandom.php on line 24

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: ‘…/random/images’ is not a valid JPEG file in /home/arctichosts/public\_html/admin/admin\_uploadrandom.php on line 24  
Problem In opening Source Image

I have GDv2.0.28.

Any ideas?
