Possible Bulk Watermaking Idea

1) save this code as showimage.php and upload to gallery root

Code:
<?php
// This script will show image with logo on it
// Supported are PNGs,GIFs,JPEGs
// ------------------------------------------------------
// call it: http://www.domain.com/showimage.php?img=<name>
// where <name> is name of image...
// example:
// http://www.domain.com/showimage.php?img=001.jpg
// ------------------------------------------------------
// You have to set parameters here:
// ------------------------------------------------------
$image_quality="100";
// quality of JPEG conpression [0-100]
// ------------------------------------------------------
$image_path="./";
// path to images
// examples:
// $image_path="./images/";
// $image_path="../../images/";
// ------------------------------------------------------
$logo_path="logo/logo.png";
// path and name of the LOGO image (PNG,GIF,JPEG)
// examples:
// $logo_path="./logos/img_logo.png";
// $logo_path="../../logos/img_logo.png"
// ------------------------------------------------------
$logo_pos_x="right";
// left, right, center
$logo_pos_y="bottom";
// top, middle, bottom
// ------------------------------------------------------
$error_not_found="File doesn't exists";
// where image is not found, show this error text
$error_not_supported="This image type isn't supported";
// where image is not supported, show this error text
$error_bg_color=array(255,255,255);
// image background color in RGB - (RED,GREEN,BLUE)
$error_text_color=array(255,0,0);
// text color in RGB - (RED,GREEN,BLUE)
// ------------------------------------------------------
// YOU DON'T HAVE TO EDIT CODE BELOW THIS LINE
// ------------------------------------------------------
// SCRIPT written by Ladislav Soukup, [root@soundboss.cz]
// ------------------------------------------------------

2) Upload your logo.png in the specified path in the script

3) Change the code in line 37 (viewimage_begin.php) with this:
Code:
<td class="viewimage"><a href="<?php $mg2->output(link) ?>" target="<?php $mg2->output(target) ?>" title="<?php echo $title ?>"><img src="showimage.php?img=<?php $mg2->output(imagefile) ?>" border="0" width="<?php $mg2->output(width) ?>" height="<?php $mg2->output(height) ?>" alt="" title="" /></a></td>
