Please help, looking for PHP script to convert equi to cube faces

Klaus, or anyone....

I am looking for a PHP script (using ImageMagick or GD) or a flash swf, to convert a equirectangular jpg to cube faces on the fly,

e.g I upload a equirectangular file by a file upload form, the server process this and creates the 6 cube faces automatically and saves them to the server.

it sounds.... so easy, but its been complicated finding any info on this for PHP :(

any help will be greatly appreciated !

Thanks

I feel sooo stupid :P

THERE is a version of ktransform for Linux and this does exactly what I need, hahahaha

Thanks :)
