<?php
// get size
$imagehw = GetImageSize($img0);
$w = $imagehw[0]; // width
$h = $imagehw[1]; // height
$maxsize = 150; // maximum size in one direction
// prevent division by zero
if ($height==0 || $width==0) exit;
// get new size according to max size
if ($height>$width) {
$new_h = $maxsize; // new height
$new_w = (int) (($maxsize * $width) / $height); // casting to int !
} else {
$new_w = $maxsize; // new width
$new_h = (int) (($maxsize * $height) / $width); // casting to int !
}
// resize image
ImageCopyResized($thumb,$img,0,0,0,0,$new_w,$new_h,$w,$h);
// new thumbnail is in $thumb
?>
