You don't even need to use the WideImage library.

Check this script here: http://bgallz.org/502/php-upload-resize-image/

You start by uploading the image and saving to a temp image file. This script runs off a form with inputs for the max height or max width. So it will then generate a new image file based on the new width/height and then copy the temp image onto the new one created on the server.

You see this with the following code:

// Create temporary image file.
$tmp = imagecreatetruecolor($newwidth,$newheight);
// Copy the image to one with the new width and height.
imagecopyresampled($tmp,$image,0,0,0,0,$newwidth,$newheight,$width,$height);
