Change this PHP script to use NETPBM instead of GD
I would like to use the following script within a larger application however by server does not support GD. However I do have the NETPBM binaries installed and working. ( for info on NETPBM go to http://netpbm.sourceforge.net )
I need the following script to be modified so that it works with the NETPBM binaries insead of using GD.
PHP Code:
function thumbimage ($image, $x, $y, $aspectratio, $resize, $cachedir){
/*##############################################
