follow these steps and you should be good to go...

Open "upload.php" and search for this -

CODE

$mmhclass->image->create_thumbnail($filename);

Should be line 53 for those following along in their hymnals...

After that line, copy and paste this into the file -

CODE

$path = "images/";
$mmhclass->image->add_watermark($extension, $path, $filename);

Save the file...

Now go into the "source\includes\" folder and open "imagemagick.php".
Goto the end of the file and go back up inside the first curly bracket ("}") and paste this into the file -

CODE

//New function to Add Watermark
        function add_watermark($extension, $path, $filename)
        {
            global $mmhclass;
            $image_upfile = $path.$filename;

            if($extension == "jpeg" || $extension == "jpg")
            {
                $watermark = imagecreatefrompng('css/watermark.png');
                imageAlphaBlending($watermark, false);
                imageSaveAlpha($watermark, true);
                $watermark_width = imagesx($watermark);
                $watermark_height = imagesy($watermark);
                $image = imagecreatetruecolor($watermark_width, $watermark_height);
                $image = imagecreatefromjpeg($image_upfile);
                $size = getimagesize($image_upfile);
                $dest_x = $size[0] - $watermark_width - 5;
                $dest_y = $size[1] - $watermark_height - 5;
                imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);

                if(@imagejpeg($image, $image_upfile, 90))
                {
                    $img_watermakred = "yes";
                }

                imagedestroy($image);
                imagedestroy($watermark);
            }

            if($extension == "png")
            {
                $watermark = imagecreatefrompng('css/watermark.png');
                $watermark_width = imagesx($watermark);
                $watermark_height = imagesy($watermark);
                $image = imagecreatetruecolor($watermark_width, $watermark_height);
                $image = imagecreatefrompng($image_upfile);
                $size = getimagesize($image_upfile);
                $dest_x = $size[0] - $watermark_width - 5;
                $dest_y = $size[1] - $watermark_height - 5;
                imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);

                if(@imagepng($image, $image_upfile))
                {
                    $img_watermakred = "yes";
                }

                imagedestroy($image);
                imagedestroy($watermark);
            }

            if($extension == "gif")
            {
                $watermark = imagecreatefrompng('css/watermark.png');
                $watermark_width = imagesx($watermark);
                $watermark_height = imagesy($watermark);
                $image = imagecreatetruecolor($watermark_width, $watermark_height);
                $image = imagecreatefromgif($image_upfile);
                $size = getimagesize($image_upfile);
                $dest_x = $size[0] - $watermark_width - 5;
                $dest_y = $size[1] - $watermark_height - 5;
                imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);

                if(@imagegif($image, $image_upfile))
                {
                    $img_watermakred = "yes";
                }

                imagedestroy($image);
                imagedestroy($watermark);
            }
        }

Save the file...

Finally, create a png file of whatever you want your watermark to be, save it as "watermark.png" and put it in the root "css" folder. If you want to name it something different or put it somewhere else, just search in the code above for "css/watermark.png" and replace it...

Now all the new photos that are uploaded will be marked with your watermark...
