hwo to save a new created image on disk

[neovantage]

Hey all,
i have created image by mixing logo and the original image. It create image and show in the same window.

I have done 3 steps for this.
First i upload an image to my server by using move_upload_file, then i resize it using class "thumbnail.class.php"

My next step was to embed company logo in it(which i already done) and save new embedded logo image to the path where i first upload the original image i mean i want to overwrite the new created image on the previously uploaded image in my step1.

Here is my code which upload image first, resize it and then create a new embed logo image

include("includes/thumbnail.class.php");
 
$file_extension=strtolower(get_ext($_FILES['photo_1']['name']));
$photo_1="images/cars/".time().'_1.'.$file_extension;
copy($_FILES['photo_1']['tmp_name'],$photo_1);
$imageproduct = new Thumbnail($photo_1, 640, 480, 100);
$imageproduct->save($photo_1);
 
$watermarklogo="images/logo.png";
$imagelogo = watermark($photo_1,$watermarklogo);
 

Here is my Watermark function code which produce the embedded logo image

function watermark($sourcefile, $watermarkfile) {
        #
        # $sourcefile = Filename of the picture to be watermarked.
        # $watermarkfile = Filename of the 24-bit PNG watermark file.
        #
 
        //Get the resource ids of the pictures
        $watermarkfile_id = imagecreatefrompng($watermarkfile);
 
        imagealphablending($watermarkfile_id, false);
        imageSaveAlpha($watermarkfile_id, true);
 
        $fileType = strtolower(substr($sourcefile, strlen($sourcefile)-3));
 
        switch($fileType) {
            case('gif'):
                $sourcefile_id = imagecreatefromgif($sourcefile);
                break;
            case('png'):
                $sourcefile_id = imagecreatefrompng($sourcefile);
                break;
            default:
                $sourcefile_id = imagecreatefromjpeg($sourcefile);
        }
        //Get the sizes of both pix  
        $sourcefile_width=imagesx($sourcefile_id);
        $sourcefile_height=imagesy($sourcefile_id);
        $watermarkfile_width=imagesx($watermarkfile_id);
        $watermarkfile_height=imagesy($watermarkfile_id);
 
        $dest_x = ( $sourcefile_width / 2 ) - ( $watermarkfile_width / 2 );
        $dest_y = ( $sourcefile_height / 2 ) - ( $watermarkfile_height / 2 );
 
        // if a gif, we have to upsample it to a truecolor image
        if($fileType == 'gif') {
            // create an empty truecolor container
            $tempimage = imagecreatetruecolor($sourcefile_width, $sourcefile_height);
               // copy the 8-bit gif into the truecolor image
            imagecopy($tempimage, $sourcefile_id, 0, 0, 0, 0, $sourcefile_width, $sourcefile_height);
              // copy the source_id int
            $sourcefile_id = $tempimage;
        }
        imagecopy($sourcefile_id, $watermarkfile_id, $dest_x, $dest_y, 0, 0, $watermarkfile_width, $watermarkfile_height);
        //Create a jpeg out of the modified picture
        switch($fileType) {    
            // remember we don't need gif any more, so we use only png or jpeg.
            // See the upsaple code immediately above to see how we handle gifs
            case('png'):
                header("Content-type: image/png");
                imagepng ($sourcefile_id);
                break;
            default:
                header("Content-type: image/jpg");
                imagejpeg ($sourcefile_id);
        }
        imagedestroy($sourcefile_id);
        imagedestroy($watermarkfile_id);
    }

there is a function "imagejpeg" in watermark function which overwrite the uploaded image but it do not work normal. it just give me a url. i am attaching picture of it.

I am giving 8 pictures upload feature at the same time. But my function only work for first image and it stops and show the url as shown in attached image.

I want that it works with every uploaded image and works with normal i mean if i will upload 8 images, it automatically upload all 8 images and refresh the page and also show the uploaded images too on that same page. But when i include that watermark function it stops me to after overwriting very first uploaded image and show the URL. i want that it works with every uploaded image and then show me the uploaded image at the same page.
