###Deploy

Put imgxp.php and cropimage.php on any PHP server with the libgd extension set to active.
In the file res/code/cropXP.js, scroll down to the function passForward and set var urlGET to a remote or local endpoint-url running cropimage.php.
In case of pic_cont_resize.html being deployed separately from the PHP scripts, it is advisable to upload the images to the PHP server as well.
