$size = 224; // the thumbnail height
    $filedir = $_SESSION["sessioname"] . '/'; // the directory for the original image
    $thumbdir = $_SESSION["sessioname"] . '/'; // the directory for the thumbnail image
    $prefix = 'small_'; // the prefix to be added to the original name
    $maxfile = '200000';
    $mode = '0666';
    $userfile_name = $_FILES['image']['name'];
    $userfile_tmp = $_FILES['image']['tmp_name'];
    $userfile_size = $_FILES['image']['size'];
    $userfile_type = $_FILES['image']['type'];
    if (isset($_FILES['image']['name'])) 
    {
        $prod_img = $filedir.$userfile_name;
        $prod_img_thumb = $thumbdir.$prefix.$userfile_name;
        move_uploaded_file($userfile_tmp, $prod_img);
        chmod ($prod_img, octdec($mode));
        $sizes = getimagesize($prod_img);
        $aspect_ratio = $sizes[0]/$sizes[1]; 
        if ($sizes[0] <= $size)
        {
            //$new_width = $sizes[0];

            $new_width = 216;
            $new_height = 224;
        }else{
            //$new_width = $size;
            //$new_height = abs($new_width/$aspect_ratio);
            $new_width = 216;
            $new_height = 224;
        }
        $destimg=ImageCreateTrueColor($new_width,$new_height) or die('Problem In Creating image');
