Below is my resize.php script. I needed to install the GD Library and did so but I am still having trouble gettint the image to process like it used to my old server.[HERE](http://go3de.com/wp-content/themes/Explorable/resize.php?w=450&img=../wp-content/themes/Explorable/panos/Pano__0000.jpg) You can see with the error reporting on there is an empty image created and the following errors display:

>
