I am trying to create PNG images on the fly
using the following code.

if(file_exists($key)) {
$diff =  time() - filemtime($key);
if($diff >= 600) {
$im = ImageCreateFromPNG($value);
$isCreated = imagePNG($im, $key, '80'); //error occurs here

I recieve the following error on the line indicated above.

imagepng: unable to open '/images/image1.png' for writing

When I run phpinfo it shows PHP as begin copiled with GD support with PNG 
enable on GD (see below)

GD Support enabled
GD Version 1.6.2 or higher
PNG Support enabled
WBMP Support enabled

The only other issue i could think of was permissions, but i have changed 
permissions to "rwx" all the way across for the directory and all files 
inside the directory.

Any one have any ideas???
