I downloaded the script just for fun and for learning some new things.
For the one who are curious what this is: http://facemash.moefelt.dk/
I wanted to install this on my localhost, but i got this: http://imageshack.us/f/41/facemashalikenotgood.png/
This is my index.php code:

</html>The css is something i made myself because the style was in the index.php i thought it was better to make a external css. So this is the main.css (got the style+code from the script)

Hi,
Thanks for downloading this script.
It's sole purpose is having fun - and learning by doing.
I would probably never had come across the ELO rating system if it hadn't been for Marc Zuckerberg
and the movie: The social network. Great movie and a lot of fun and inspiration!
The script is not really in a production state and there is plenty room for improvement (if you make any
just mail me so I can update the source with your addons).
To get you going:
1) upload all files to your website/testspace or whereever you wanna play with it.
2) setup your database - look in the file: mysql.php
3) execute this SQL to setup your database tables:
CREATE TABLE IF NOT EXISTS `battles` (
`battle_id` bigint(20) unsigned NOT NULL auto_increment,
`winner` bigint(20) unsigned NOT NULL,
`loser` bigint(20) unsigned NOT NULL,
PRIMARY KEY (`battle_id`),
KEY `winner` (`winner`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
CREATE TABLE IF NOT EXISTS `images` (
`image_id` bigint(20) unsigned NOT NULL auto_increment,
`filename` varchar(255) NOT NULL,
`score` int(10) unsigned NOT NULL default '1500',
`wins` int(10) unsigned NOT NULL default '0',
`losses` int(10) unsigned NOT NULL default '0',
PRIMARY KEY (`image_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
4) place all your images that's up for battle in the /imagees/ folder.
5) run the /install_images.php from your site to install all images from your folder into your database.
6) have fun!
Best regards from Denmark,
/AndersSorry for the long post, I wanted to sort this out :) Thank you
