Whether you have Unix or NT/2000, running Perl, PHP, or ASP/VBScript, prevents someone from "stealing" the URL to reference pictures located on your website. I got tired of people linking to pictures stored on my web server, and thus developed this program to stop that.

• What's new in the latest version?
• See these scripts in action!
• System Requirements
• Order the scripts you need!
• Disclaimers

Multiple "valid" domains are now supported so you can allow other specified domains to link to your images.

(NOTE that my ISP does not support ASP, and thus I cannot show you the ASP scripts in action. The ASP scripts work exactly the same way.)

1. View the images and click on the "link" to the image below to see the linked image.
2. Copy the entire HTML SOURCE code next to the corresponding images in a document on your webserver.
3. View the webpage you just saved on your webserver. Notice the images are now completely different? MAKE SURE TO CLEAR YOUR BROWSER's CACHE AND/OR HOLD DOWN THE "SHIFT" KEY AND CLICK "RELOAD" WHEN YOU VIEW THIS PAGE ON YOUR SERVER. This is to make sure your browser doesn't used the cached images from viewing them on MY site.

PHP HTML IMG tag demo:	<IMG SRC="http://www.davelozinski.com/scripts/bwp/bwp.php?image=lozad&type=image">
PHP HTML link-to-image demo: Click Me!	<A HREF="http://www.davelozinski.com/scripts/bwp/bwp.php?image=lozad&type=link">Click Me!</A>
Perl HTML IMG tag demo:	<IMG SRC="http://www.davelozinski.com/cgi-bin/bwp/bwp.pl?image=lozad&type=image">
Perl HTML link-to-image demo: Click Me!	<A HREF="http://www.davelozinski.com/cgi-bin/bwp/bwp.pl?image=lozad&type=link">Click Me!</A>

These scripts work in one of two ways. They prevent people from linking to images on your website:

1. you reference through the HTML IMG tag.
2. you simply link to through an HTML Anchor tag.

You can even program this script to NOT return any image at all!

The picture formats this script helps protect are gifs, jpegs, bitmaps, png files. The program can be easily expanded to accomodate others as long as you know the MIME type!

ASP

• Windows NT/2000 Server running IIS 4.0 or later
• Standard set of Environmental Variables
• ADO Version 2.5 or later! VERY IMPORTANT! To see if your server has ADO version 2.5 or later, save the following ASP code on your server and run it:
  

  <!--METADATA TYPE="typelib" UUID="00000205-0000-0010-8000-00AA006D2EA4" NAME="ADODB Type Library" --> <% Set objConn = Server.CreateObject("ADODB.Connection") Response.Write "This Server's ADO Version: " & objConn.Version Set objConn = Nothing %>

Perl

• Unix or Windows NT/2000 Webserver
• Standard set of Environmental Variables
• Perl version 5.003 (or greater) for Unix, or ActiveState's Active Perl 5.6.1 (or greater) for Windows NT/2000.

PHP

• Unix or Windows NT/2000 Webserver
• Standard set of Environmental Variables

• The ASP version has been tested on Windows 2000 and IIS 5.0.



• The Perl versions have been tested on Unix and Windows 2000 running Perl 5.003. On Unix, the webserver used was Apache; Windows 2000 ran IIS 5.0.



• The PHP versions have been tested on Unix and Windows 2000 running PHP 4.2.3. On Unix, the webserver used was Apache; Windows 2000 ran IIS 5.0.
