Assuming the directory is writeable, your uploaded file is the variable
$file and $height is the new height of your resampled image

$src_img = imagecreatefromjpeg($file);
$new_h = $height;
$new_w = ($new_h*imagesx($src_img))/imagesy($src_img);
$dst_img = imagecreatetruecolor($new_w,$new_h);
imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $new_w, $new_h,
imagesx($src_img), imagesy($src_img));
imagejpeg($dst_img, "reduced_".$file, 100);
