UPS ... sorry ...
if using $height/$h and $width/$w I should it in the whole script ...
<?php
// get size
//
$w = 640; // width
$h = 480; // height
$maxsize = 150; // maximum size in one direction
// prevent division by zero
if (($h ==0) || ($w==0)) exit;
// get new size according to max size
if ($h>$w) {
$new_h = $maxsize; // new height
$new_w = (int) (($maxsize * $w) / $h); // casting to int !
} else {
$new_w = $maxsize; // new width
$new_h = (int) (($maxsize * $h) / $w); // casting to int !
}
// resize image
echo "newsize: $new_w x $new_h";
// new thumbnail is in $thumb
?>
now that should do ! ;-)
