I have a script which upload image to the server and resize them when uploading))
the script give a max width=200px also max height=200px))for i uploaded image..
i would like if some one can help me modify it,in such away that if Only width must be Max=200px but for height ratio,whichever even up to 500px depending with the image uploaded..
below is the code..
//make sure this directory is writable!
		$path_thumbs ='c:/wamp/www/thumb';
		//the new width of the resized image, in pixels.
		$img_thumb_width = 200; // 

		$extlimit = "yes"; //Limit allowed extensions? (no for all extensions allowed)
		//List of allowed extensions if extlimit = yes
		$limitedext = array(".gif",".jpg",".png",".JPG",".JPEG",".jpeg",".bmp");
		//the image -> variables
	    $file_type = $_FILES['vImage']['type'];
        $file_name = $_FILES['vImage']['name'];
        $file_size = $_FILES['vImage']['size'];
        $file_tmp = $_FILES['vImage']['tmp_name'];

        //check if you have selected a file.
           echo "Error: Make sure Your Image is not More 2MB before You Upload!. <br><a href=profilephoto.php>back</a>";
           exit(); //exit the script and don't process the rest of it!
       //check the file's extension
       $ext = strrchr($file_name,'.');
       $ext = strtolower($ext);
       //uh-oh! the file extension is not allowed!
       if (($extlimit == "yes") && (!in_array($ext,$limitedext))) {
          echo "Wrong file extension.  <br>--<a href=profilephoto.php>back</a>";
       //so, whats the file's extension?
       $getExt = explode ('.', $file_name);
       $file_ext = $getExt[count($getExt)-1];

       //create a random file name
       $rand_name = md5(time());
       $rand_name= rand(0,999999999);
       //the new width variable
       $ThumbWidth = $img_thumb_width;

       //keep image type
          if($file_type == "image/pjpeg" || $file_type == "image/jpeg"){
               $new_img = imagecreatefromjpeg($file_tmp);
           }elseif($file_type == "image/x-png" || $file_type == "image/png"){
               $new_img = imagecreatefrompng($file_tmp);
           }elseif($file_type == "image/gif"){
               $new_img = imagecreatefromgif($file_tmp);
           //list the width and height and keep the height ratio.
           list($width, $height) = getimagesize($file_tmp);
           //calculate the image ratio
           $imgratio=$width/$height;   //From here is where i want the modification to Go))))
            if ($imgratio>1){
              $newwidth = $ThumbWidth;
              $newheight = $ThumbWidth/$imgratio;
                 $newheight = $ThumbWidth;
                 $newwidth = $ThumbWidth*$imgratio;
           //function for resize image.
           if (function_exists(imagecreatetruecolor)){
           $resized_img = imagecreatetruecolor($newwidth,$newheight);
                 die("Error: Please make sure you have GD library ver 2+");
           //the resizing is going on here!
           imagecopyresized($resized_img, $new_img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
           //finally, save the image
           ImageJpeg ($resized_img,"$path_thumbs/$rand_name.$file_ext");
           ImageDestroy ($resized_img);
           ImageDestroy ($new_img);

        //ok copy the finished file to the thumbnail directory
		move_uploaded_file ($file_tmp, "$path_big/$rand_name.$file_ext");
