General Support: Generate Cruft-Free URLs doesn't seem to work

Hi,

I am looking for a straight forward script to use on some image based websites I run. Plogger really seems to be a good choice, but I do have a few questions (I will make a seperate post for each one over time)

My first is regarding search engine friendly urls - I have activated "Generate Cruft-Free URLs" but I still get a url that looks like this ?level=album&id=2

I can edit my .htaccess file directly and currently have this:

# BEGIN Plogger
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^.*$ - [S=2]
RewriteRule feed/$ plog-rss.php?path=%{REQUEST_URI} [L]
RewriteRule ^.*$ index.php?path=%{REQUEST_URI} [L]
</IfModule>
# END Plogger

Which was taken and adapted from another post on the forum, but the .htaccess file was already populated with similar commands.
I have Plogger installed in the root diretory so I changed the Rewrite Base section.

The only time I get a search engine friendly url is for the final image - images/iphone_wallpapers/3d_and_abstract/paper-clips-wallpaper-002.jpg but it is important for every section of the site to be search engine friendly.

Any help would be greatly appreciated.

Regards
Stephen
