Creating thumbs script - slight change needed

[ukscotth]

Hi,

 

I have this script for creating thumbnails which works fine but can someone please show me how to modify it so instead of it changeing the width every time it changes either the width or height, whichever one is bigger. So if i set it to say 150, neither the height or width will ever be bigger than 150.

 

Also so it doesnt increase the size if both the width and height are already lower than 150.

 

Hope that makes sense and i hope someone can help

 

<?php
function makeThumbs( $pathToImages, $pathToThumbs, $thumbWidth ) {

  $dir = opendir($pathToImages);

  while (false !== ($fname = readdir($dir))) {

    $info = pathinfo($pathToImages . $fname);

    if (strtolower($info['extension']) == 'jpg') {
       
    	echo "Creating thumbnail for $fname <br />";

    $img = imagecreatefromjpeg($pathToImages . $fname);
    
    $width = imagesx($img);
    
    $height = imagesy($img);
      
    $new_width = $thumbWidth;
    
    $new_height = floor($height * ($thumbWidth / $width));
    
    $tmp_img = imagecreatetruecolor($new_width, $new_height);

      	imagecopyresized( $tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height );

      	imagejpeg( $tmp_img, "{$pathToThumbs}{$fname}");
    }
    
  }

  closedir($dir);
  
}

makeThumbs("pictures/","thumbs/",150);
?>
