```php

<?
$id = $_GET['id'];
if($id){
@mysql_connect("localhost","username","pswd");
    @mysql_select_db("db_name");
$query ="SELECT file,type FROM db_table WHERE id=$id";	
$result = @mysql_query($query);
$data = @mysql_result($result,0,"file");
$type = @mysql_result($result,0,"type");

Header( "Content-type: $type");
echo $data;
};

like [http://www.mysite.com/get\_img.php?id=0](http://www.mysite.com/get_img.php?id=0)

doesnt work but every field after that works fine

[http://www.mysite.com/get\_img.php?id=1](http://www.mysite.com/get_img.php?id=1)  
[http://www.mysite.com/get\_img.php?id=2](http://www.mysite.com/get_img.php?id=2)  
[http://www.mysite.com/get\_img.php?id=3](http://www.mysite.com/get_img.php?id=3)
