Dynamic Image With PHP
Normally if we want to use image on HTML we must using IMG tag with direct link of any image. But now with PHP we can do a little tricks. Just for fun and maybe it’s usefull for you. Who knows 
Let’s get started.
This is normally IMG tag.
<img src=”http://domain.com/your-image-url.gif” />
But now we change like this.
<img src=”http://domain.com/img.php?img=3″ />
That’s just an example. So here is the code
<?php
/*
By using this script you agree not to remove the link of coded by Ferri
Homepage : http://smileylover.com
Friendster Smiley, MySpace Smiley, Forum Smiley.
*/error_reporting(E_ALL);
if(isset($_GET['img'])) {
$img = $_GET['img'];
if(get_magic_quotes_gpc())
{
$img = stripslashes($img);
}$image = array
(’1′ => ‘URL-IMAGE-1′,
’2′ => ‘URL-IMAGE-2′,);header( “Content-type: image/gif” );
@readfile (“$image[$img]“);}
?>
Save code above into img.php then set your image url into array. Example you set in array 1 -> http://img368.imageshack.us/img368/9987/11lq3.gif and to call it with php set this code to get the same image.
http://domain.com/img.php?img=1
It can hide the real image url or hide long url. So enjoy it
