I have this code here:

?>

But when I enable it says

Warning: file_put_contents(/absolute/path/to/forum/steamtools/icons/avatar_full1.jpg) [function.file-put-contents]: failed to open stream: No such file or directory in [path]/steamtools/steam_function.php on line 100

Warning: file_put_contents(/absolute/path/to/forum/steamtools/icons/avatar_small1.jpg) [function.file-put-contents]: failed to open stream: No such file or directory in [path]/steamtools/steam_function.php on line 100

I asked how I could fix this and someone just said use this
print SERVER['DOCUMENT_ROOT']

I dont know what it means can anyone help?

Install instructions but i dont get why its not working

1. create a subfolder named 'steamtools' in the folder where your forum (index.php) resides
2. create a subfolder in 'steamtools' named 'icons'
3. chmod 'icons' to 755
4. open steam_function.php in a plain text editor like notepad, and replace the paths in lines 58 and 62 accordingly. Note that these paths need to be absolute and not relative!
5. upload steam_function.php to 'steamtools'
6. create a sinlge-line text box custom profile field named 'Steam ID' (note this is case sensitive, if you want to change this, change the occurring instances in the .xml and .php files as well)
7. create a single-selection radio buttons custom profile field named 'Steam Community' with these two values : 'Yes, make the links visible' and 'No, hide the links' (note this is all case sensitive, if you want to change this, change the occurring instances in the .xml and .php files as well)
8. import product-steam2friends.xml in the admin panel

Did you actually leave this in your code?

/absolute/path/to/forum/steamtools/icons/avatar_full

If so, that is your problem. You are supposed to change that to be your absolute path.

yea sorry that's what I did not understand what does that mean?

open steam_function.php in a plain text editor like notepad, and replace the paths in lines 58 and 62 accordingly. Note that these paths need to be absolute and not relative!

Edit the paths in line 58 and 62 accordingly. Note that these paths should be absolute, not relative.
To enable memcached, uncomment the commented blocks below (lines 22-31 and 86-89) and replace <port> with the portnumber on which memcached is listening. The default is 11211.

How do I fix that?

Ever server has a path to a file. You start at the very top and go down via directories (just like on your computer). So, it's the path from the top. You start at the top, then go into a directory called "home", then from there to "sitename", then from there to "public_html", then from there to.... etc. So far, the path in that example is /home/sitename/public_html/

Oh ok thanks,

On here though I have my paths down correctly but shows the links no pictures

            if (($p1=strpos($data,'<div class="avatarFull">'))!==false){
                $p1=strpos($data,'<',$p1+24);
                $p2=strpos($data,'>',$p1+1);
                $tmp=substr($data,$p1,$p2-$p1+1);
                $link_full=get_link_src($tmp);
                gaben_downloadz0r($link_full,'/home/users/public_html/forums/steamtools/icons/avatar_full'.$ret['uid'].'.jpg');
                $ret['img_full']=$tmp;
                $tmp=str_replace('_full','',$tmp);
                $link_small=get_link_src($tmp);
                gaben_downloadz0r($link_small,'/home/users/public_html/forums/steamtools/icons/avatar_small'.$ret['uid'].'.jpg');
                $ret['img_small']=$tmp;

But it said correct lines on 58 and 62 which is

Line 58: ['img_full']

Line 62: ['img_small']

If the script isn't working after you got the paths correct, then you really should be asking them for help. I know absolutely nothing about that script.
