on your cpanel there is an option for hotlinking. If you need help icq me tom and i can set it up for you.

Redirect all nonblank, non[yourdomain], referrers to http://goatse.ca/hello.jpg :D

Or, if you don't want to be a dick, just put together some generic pic saying "see this photo and others at [yourdomain]" with some half naked chick in the background.

if someone wants to modify my htaccess i would be most appreciative and im sure others would find it a usefull resource..

THE FOLLOWING is a script/htaccess to add a watermark to all your images.. It would be nice to modify it so it only watermarked the images when they are hotlinked..



this is what the htaccess should look like

AddHandler watermarked .jpg
AddHandler watermarked .jpeg
AddHandler watermarked .gif
AddHandler watermarked .png

Action watermarked http://www.yoursite.com/watermarkscript.php

then the watermarkscript.php should look like this

<?php
$watermark = "watermark.png";
$image = $_SERVER["PATH_TRANSLATED"];

if (empty($image)) die();

if (!file_exists($image)) {
   header("404 Not Found");
   echo "File Not Found."; die();
}

$outputType = getFileType($image);

watermark($image, $watermark, $outputType);

/**
   Outputs the image $source with $watermark in the lower right corner.
   @param $source the source image
   @param $watermark the watermark to apply
   @param $outputType the type to output as (png, jpg, gif, etc.)
                      defaults to the image type of $source if left blank
*/
function watermark($source, $watermark, $outputType="") {
   $sourceType = getFileType($source);
   $watermarkType = getFileType($watermark);

   if (empty($outputType)) $outputType = $sourceType;
   
   header("Content-type:image/$outputType");

   // Derive function names
   $createSource = "ImageCreateFrom".strtoupper($sourceType);
   $showImage = "Image".strtoupper($outputType);
   $createWatermark = "ImageCreateFrom".strtoupper($watermarkType);

   // Load original and watermark to memory
   $output = $createSource($source);
   $logo = $createWatermark($watermark);
   ImageAlphaBlending($output, true);

   // Find proper coordinates so watermark will be in the lower right corner
   $x = ImageSX($output) - ImageSX($logo);
   $y = ImageSY($output) - ImageSY($logo);

   // Display
   ImageCopy($output, $logo, $x, $y, 0, 0, ImageSX($logo), ImageSY($logo));
   $showImage($output);

   // Purge
   ImageDestroy($output);
   ImageDestroy($logo);
}

function getFileType($string) {
   $type = strtolower(eregi_replace("^(.*)\.","",$string));
   if ($type hahahaha "jpg") $type = "jpeg";
   return $type;
}

( hahaha should read == )

then just place a watermark.png that you want on every picture in the same directory as the watermarkscript.php
