first time use of htaccess and mod_rewrite

[wrathican]

hey people im trying to use mod_rewrite to change the look of a url

this is the original url: http://localhost/gallery.php?func=viewpic&alid=2&picid=11 (ignore locahost)

this is the rewritten url: http://localhost/viewpic/2/11.html

 

but for some reason its not working on my localhost (says internal server error) or on my live site(no erros, but no rewritten url)

 

this is the code im using.

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)/([^/]*)\.html$ /gallery.php?func=$1&alid=$2&picid=$3 [L]

 

any ideas why its not woking.

Did you make sure mod rewrite is enabled on your localhost, in the php.ini file?
