    $destination_folder = 'D:/Websites';
    $watermark_png_file = 'watermark.png'; //watermark png file
    
    $image_name = $_FILES['image_file']['name']; //file name
    $image_size = $_FILES['image_file']['size']; //file size
    $image_temp = $_FILES['image_file']['tmp_name']; //file temp
    $image_type = $_FILES['image_file']['type']; //file type

    switch(strtolower($image_type)){ //determine uploaded image type
            //Create new image from file
            case 'image/png':
                $image_resource =  imagecreatefrompng($image_temp);
                break;
            case 'image/gif':
                $image_resource =  imagecreatefromgif($image_temp);
                break;          
            case 'image/jpeg': case 'image/pjpeg':
                $image_resource = imagecreatefromjpeg($image_temp);
                break;
            default:
                $image_resource = false;
        }
    
    if($image_resource){
        //Copy and resize part of an image with resampling
        list($img_width, $img_height) = getimagesize($image_temp);
        
        //Construct a proportional size of new image
        $image_scale        = min($max_size / $img_width, $max_size / $img_height);
        $new_image_width    = ceil($image_scale * $img_width);
        $new_image_height   = ceil($image_scale * $img_height);
        $new_canvas         = imagecreatetruecolor($new_image_width , $new_image_height);
        $text_color = imagecolorallocate($new_canvas, 233, 14, 91);
        imagestring($new_canvas, 1, 5, 5,  'A Simple Text String', $text_color);

        if(imagecopyresampled($new_canvas, $image_resource , 0, 0,0, 0, $new_image_width, $new_image_height, $img_width, $img_height))
        {
            
            if(!is_dir($destination_folder)){
                mkdir($destination_folder);//create dir if it doesn't exist
            }
            
            //center watermark
            $watermark_left = ($new_image_width/2)-(2/2); //watermark left            
            $watermark_bottom = ($new_image_height/2)-(2/2); //watermark bottom

            $watermark = imagecreatefrompng($watermark_png_file); //watermark image
            imagecopy($new_canvas, $watermark, $watermark_left, $watermark_bottom, 0, 0, 160, 128); //merge image
            
            //output image direcly on the browser.
            header('Content-Type: image/jpeg');
            
            
            imagejpeg($new_canvas, NULL , 90);
            
            //Or Save image to the folder
            //imagejpeg($new_canvas, $destination_folder.'/'.$image_name , 90);
            
            //free up memory
            imagedestroy($new_canvas);
            imagedestroy($image_resource);
            die();
        }
    }
