Automatically watermark all uploaded photos (给所有上传的相片加水印)

Hello,

This mod automatically watermark all uploaded photos.

Price: FREE, enjoy.

You will have to edit 3 files:

1. ../classes/image.class.php - watermark function.
2. ../modules/upload/photo.php - when upload photos from upload page.
3. ../modules/album/addphotos.php - when add photos to existing album.
---------------------------------------------

1. In "../classes/images.class.php" find (~ line 195):

public function watermark()
	{		
	}

and replace with:

	public function watermark($SourceFile, $WatermarkFile, $SaveToFile = NULL)
	{
		$watermark = @imagecreatefrompng($WatermarkFile) 
		    or exit('Cannot open the watermark file.');
		imageAlphaBlending($watermark, false);
		imageSaveAlpha($watermark, true);
		$image_string = @file_get_contents($SourceFile) 
			or exit('Cannot open image file.');
		$image = @imagecreatefromstring($image_string)
			or exit('Not a valid image format.');
		$imageWidth=imageSX($image);
	    $imageHeight=imageSY($image);
		$watermarkWidth=imageSX($watermark);
		$watermarkHeight=imageSY($watermark);
		$coordinate_X = ( $imageWidth - 5) - ( $watermarkWidth);
		$coordinate_Y = ( $imageHeight - 5) - ( $watermarkHeight);
		imagecopy($image, $watermark, $coordinate_X, $coordinate_Y, 0, 0, $watermarkWidth, $watermarkHeight);
		if(!($SaveToFile)) header('Content-Type: image/jpeg');
		imagejpeg ($image, $SaveToFile);
		imagedestroy($image);
		imagedestroy($watermark);
		if(!($SaveToFile)) exit;
	}

2. In "../modules/upload/photo.php" find (~ line 90):

    $dst        = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
    $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
    $image->resize(true, true);

and after "$image->resize(true, true);" insert this:

	$image_location = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg'; 
		// Locate the watermark file wherever you choose (remember PNG format). I put in ../media/photos/watermark.png
	$watermark_location =  $config['BASE_DIR']. '/media/photos/watermark.png';
	$save_watermarked_file_to = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
	$image->watermark($image_location, $watermark_location, $save_watermarked_file_to);

3. In "../modules/album/addphotos.php" find (~ line 40):

    $dst            = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
    $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
    $image->resize(true, true);

and like the previous after "$image->resize(true, true);" insert this:

	$image_location = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg'; 
		// Locate the watermark file wherever you choose (remember PNG format). I put in ../media/photos/watermark.png
	$watermark_location =  $config['BASE_DIR']. '/media/photos/watermark.png';
	$save_watermarked_file_to = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
	$image->watermark($image_location, $watermark_location, $save_watermarked_file_to);

!!! ++$photos; must be below the pasted code.

There is screens from thats files after mods.

image.class.php

1. ../classes/image.class.php - watermark function.
i did a copy

2. ../modules/upload/photo.php - when upload photos from upload page.

    $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
    $image->resize(true, true);
                    $dst        = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
                    $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
                    $image->resize(true, true);
                     $image_location = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg'; 
        // Locate the watermark file wherever you choose (remember PNG format). I put in ../media/photos/watermark.png
    $watermark_location =  $config['BASE_DIR']. '/media/photos/watermark.png';
    $save_watermarked_file_to = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
    $image->watermark($image_location, $watermark_location, $save_watermarked_file_to);  

3. ../modules/album/addphotos.php - when add photos to existing album.

                $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
                $image->resize(true, true);  
                $dst            = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
                $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
                $image->resize(true, true);
$image_location = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg'; 
        // Locate the watermark file wherever you choose (remember PNG format). I put in ../media/photos/watermark.png
    $watermark_location =  $config['BASE_DIR']. '/media/photos/watermark.png';
    $save_watermarked_file_to = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
    $image->watermark($image_location, $watermark_location, $save_watermarked_file_to);  

                ++$photos;

think somewhere there is error

                $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
                $image->resize(true, true);  
                $dst            = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
                $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
                $image->resize(true, true); 

in my code not 2x "'MAX_WIDTH', 575, 0"

its looks like you added that to:

    $dst        = $config['BASE_DIR']. '/media/photos/' .$photo_id. '.jpg';
    $image->process($src, $dst, 'MAX_WIDTH', 575, 0);
    $image->resize(true, true);  

but I was thinking to be pasted after that
