This code originally came from [ Register or login to view links on this board. ] They were discussing it on a post that is located here:

This code should allow a watermark on images in coppermine galleries using imagemagick. The watermarks are different if a user is registered or a guest.

The way this works is you have to create 2 transparent png files called watermark.png and watermark2.png. These have to be uploaded to your modules/coppermine directory. You then create two files one called wm.php with the following code:

<?
//define('IN_COPPERMINE', true);
//require('include/init.inc.php');

header('Content-Type: image/jpeg');
header('Content-Disposition: inline; filename=file.jpg');

$pid = $_REQUEST["pid"];
$mode = $_REQUEST["mode"];

$dbhost = "Put your database host IP here";
$dbuname = "DB user name";
$dbpass = "DB password";
$dbname = "nuke";
$prefix = "nuke";
$normal_pfx = "normal_";
$thumb_pfx = "thumb_";
$impath = "Dir ath to imagemagic";
$TABLE_PREFIX  = "cpg_";
$mainpath = "Dir path to the root of you web site";

$sql = "SELECT * FROM ".$TABLE_PREFIX."pictures WHERE pid=$pid";
$db = mysql_connect($dbhost, $dbuname, $dbpass);
mysql_select_db($dbname, $db);


$result = mysql_query($sql, $db);
$row = mysql_fetch_array($result);

$pic_prefix = array(
    'thumb' => $thumb_pfx,
    'normal' => $normal_pfx,
    'fullsize' => ''
);


$cmd = "{$impath}composite.exe -compose over -gravity Center \"".realpath("./watermark.png")."\" \"".$mainpath.'/'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"]."\" jpg:-";

passthru ($cmd, $output);

echo $output;
?>


The other wm2.php with the code:

<?
//define('IN_COPPERMINE', true);
//require('include/init.inc.php');

header('Content-Type: image/jpeg');
header('Content-Disposition: inline; filename=file.jpg');

$pid = $_REQUEST["pid"];
$mode = $_REQUEST["mode"];

$dbhost = "Put your database host IP here";
$dbuname = "DB user name";
$dbpass = "DB password";
$dbname = "nuke";
$prefix = "nuke";
$normal_pfx = "normal_";
$thumb_pfx = "thumb_";
$impath = "Dir ath to imagemagic";
$TABLE_PREFIX  = "cpg_";
$mainpath = "Dir path to the root of you web site";

$sql = "SELECT * FROM ".$TABLE_PREFIX."pictures WHERE pid=$pid";
$db = mysql_connect($dbhost, $dbuname, $dbpass);
mysql_select_db($dbname, $db);


$result = mysql_query($sql, $db);
$row = mysql_fetch_array($result);

$pic_prefix = array(
    'thumb' => $thumb_pfx,
    'normal' => $normal_pfx,
    'fullsize' => ''
);


$cmd = "{$impath}composite.exe -compose over -gravity Center \"".realpath("./watermark2.png")."\" \"".$mainpath.'/'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"]."\" jpg:-";

passthru ($cmd, $output);

echo $output;
?>


Both of these files load into the modules/coppermine directory.

Then you need to modify the "\coppermine\include\functions.inc.php" with the following code:

Look for "function get_pic_url"

// Return the url for a picture, allows to have pictures spreaded over multiple servers
function get_pic_url(&$pic_row, $mode)
{
    global $CONFIG,$USER_DATA,$cat;
    static $pic_prefix = array();
    static $url_prefix = array();
    if (!count($pic_prefix)) {
        $pic_prefix = array('thumb' => $CONFIG['thumb_pfx'],
            'normal' => $CONFIG['normal_pfx'],
            'fullsize' => ''
            );
        $url_prefix = array(0 => $CONFIG['fullpath'],
            );
    }
    //return path2url($pic_row['filepath'] . $pic_prefix[$mode] . $pic_row['filename']);
    //Begin mod  mike
     //echo $cat;
     //echo $USER_DATA['group_id'];
    if((($mode == "normal") || ($mode == 'fullsize')) && ($CONFIG['thumb_method']=='im') && (($cat != '22') && ($cat != '23') && ($cat != '-56') && ($cat != '-57') && ($cat != '-58') && ($cat != '-59') && ($cat != '-60') && ($cat != '-61'))  ){

      If(($USER_DATA['group_id'] == 2) || ($USER_DATA['group_id'] == 1)){
        // return the url to the wm script
        return "modules/coppermine/wm.php?pid=".$pic_row["pid"]."&mode=".$mode;
      }else{
        return "modules/coppermine/wm2.php?pid=".$pic_row["pid"]."&mode=".$mode;
       }

   }else{
      // it's a thumb, don't bother wm'ing
      return path2url($pic_row['filepath'] . $pic_prefix[$mode] . $pic_row['filename']);

   }
   //end mod
}


I have made what I am fairly sure are the correct changes in wm.php and wm2.php by the following:

$dbhost = "localhost";
$dbuname = "";
$dbpass = "";
$dbname = "night-blues_com_-_nuke";
$prefix = "nuke";
$normal_pfx = "normal_";
$thumb_pfx = "thumb_";
$impath = "/usr/bin/";
$TABLE_PREFIX  = "nuke_cpg_";
$mainpath = "/var/www/html/nuke";


Any help could be appreciated with this. It looks like the images aren't being called up correctly, because after loading this, the thumbnails work, but the normal images don't.
