Help Editing This Function

Hi,

What i wish to do is within this function is check if the size of the original image to see if it is smaller than $ImgWidth and if so then upload the orginal and not the resized big image.

Here is the code:

function uploadimage($value)
{
	$file_type = $value['type'];
	$file_name = $value['name'];
	$file_size = $value['size'];
	$file_tmp = $value['tmp_name'];

//check file extension
       $ext = strrchr($file_name,'.');
       $ext = strtolower($ext);
       if (($extlimit == "yes") && (!in_array($ext,$limitedext))) {
          echo "Wrong file extension.  <br>--<a href=\"$_SERVER[PHP_SELF]\">back</a>";
          exit();
       }

	//get the file 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);
	//get the new width variable.
	$ThumbWidth = 150;
	$ImgWidth = 640;

	//keep image type
	if($file_size){
		if($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 width and height and keep height ratio.
		list($width, $height) = getimagesize($file_tmp);
				
		$bigger = ($width >= $height) ? $width : $height; 
    
		$imgratio = $bigger / $ThumbWidth;
		$newwidth = intval($width / $imgratio);
		$newheight = intval($height / $imgratio);
		
		$imgratio = $bigger / $ImgWidth;
		$newwidth2 = intval($width / $imgratio);
		$newheight2 = intval($height / $imgratio);
		
		
		$resized_img = imagecreatetruecolor($newwidth, $newheight);
		imagecopyresized($resized_img, $new_img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
		
		$resized_img2 = imagecreatetruecolor($newwidth2, $newheight2);
		imagecopyresized($resized_img2, $new_img, 0, 0, 0, 0, $newwidth2, $newheight2, $width, $height);
		
		imagejpeg($resized_img, "imgtemp/thumbs/".$rand_name.".".$file_ext);  
		imagejpeg($resized_img2, "imgtemp/big/".$rand_name.".".$file_ext);

		//save images
		ftpupload($rand_name.".".$file_ext, "imgtemp/thumbs/".$rand_name.".".$file_ext, "/httpdocs/uploads/images/thumbs/");
		ftpupload($rand_name.".".$file_ext, "imgtemp/big/".$rand_name.".".$file_ext, "/httpdocs/uploads/images/big/");
		
		unlink("imgtemp/big/".$rand_name.".".$file_ext);
		unlink("imgtemp/thumbs/".$rand_name.".".$file_ext);
		
		imagedestroy($resized_img);
		imagedestroy($resized_img2);
		imagedestroy($new_img);

	}	
	$value = $rand_name.".".$file_ext;
	return $value;
}

Thanks in Advanced.
