this code sets the $newwidth=600
next I want to set the $newheight=600
If the image is 1200 height and 2 width then this image will be larger than 600 height
I want this image to fit in a 600 by 600 foot box
// This is the temporary file created by PHP
//$uploadedfile = $_FILES['uploadfile']['tmp_name'];
// Create an Image from it so we can do the resize
$src = imagecreatefromjpeg($uploadedfile);
// Capture the original size of the uploaded image
// For our purposes, I have resized the image to be
// 600 pixels wide, and maintain the original aspect
// ratio. This prevents the image from being "stretched"
// or "squashed". If you prefer some max width other than
// 600, simply change the $newwidth variable
// this line actually does the image resizing, copying from the original
// image into the $tmp image
// now write the resized image to disk. I have assumed that you want the
// resized, uploaded image file to reside in the ./images subdirectory.
//$filename = "images/". $_FILES['uploadfile']['name'];
$filename = "uploaded/newfile.jpg";
imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request
// has completed.
