Hotlinking custom modification ?

Steptoe · Involved Joined: Oct 09, 2004 Posts: 288

Hey guys, see u are all still kicking around, keeping well I hope.
I have been playing with
1/ .htaccess and
2/ .htaccess/showpic.php
They both work but cant figure out how to make them work as I would like.

the simple .htaccess method described in older posts and below just replaces the hotlinked file with a gif

What I would like to do is have that hotlink pic

(or preferible site link banner )

With a hyper link to kakariki.net home page
And words below like "hotlink bandwidth theft is not permiited, if you wish to visit us clk the banner above" A alt tag with site description
Sort of the same as the code in the link to us block raven has on the home page

The codes I have been playing with are
1/

Code:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?kakariki.net/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?kakariki.sytes.net/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?babelfish.altavista.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?translate.google.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?yahoo.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?yahoo.net/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?msn.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?google.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?msn.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?windowslivetranslator.com/.*$ [NC]
RewriteRule \.(gif|jpg)$ /hotlink.jpg [R,L]

2/ in .htaccess

Code:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} .*jpg$.*gif$.*png$ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !kakariki\.net [NC]
RewriteCond %{HTTP_REFERER} !kakariki\.sytes\.net [NC]
RewriteCond %{HTTP_REFERER} !google\. [NC]
RewriteCond %{HTTP_REFERER} !search\?q=cache [NC]
#RewriteRule (.*) /showpic.php?pic=$1

And a new file showpic.php

Code:

<?php
header("Content-type: text/html");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-store, no-cache,
must-revalidate");
header("Cache-Control: post-check=0, pre-check=0",
false);
header("Pragma: no-cache");
$pic = strip_tags( $_GET['pic'] );

if ( ! $pic ) {
die("No picture specified.");
}
?>

<html>
<head>
<title><?php echo($pic); ?></title>
<meta

</head>
<body>

<img src="/<?php echo($pic); ?>" alt="Image">

I get what I want to present instead of the hotlinked file

But doesnt work where the hot link is??
I suspect it is the last line in the ,htaccess

Code:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} .*jpg$.*gif$.*png$ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !kakariki\.net [NC]
RewriteCond %{HTTP_REFERER} !kakariki\.sytes\.net [NC]
RewriteCond %{HTTP_REFERER} !google\. [NC]
RewriteCond %{HTTP_REFERER} !search\?q=cache [NC]
RewriteRule (.*) /showpic.php?pic=$1

O as usual Im trying to do something with something I have no idea ...
Again Rolling Eyes

Help please?

Bump?
Is it actually possible to do what I would like?

Steptoe, bump? Shocked

I think you are on the right track. Unfortunately, I am not sure about the second line within your .htaccess. That may very well be correct as far as I know, but my first glance at it made me unsure of it. Maybe try this:

RewriteCond %{REQUEST_FILENAME} ^.*\.(jpg|gif|png)$ [NC]

In addition, depending upon where these image path names are coming from, you may want to consider doing some input cleansing on the $pic variable as you could be opening yourself up for all sorts of exploitation.
