htaccess rewrite problem

[Benji6996]

I am trying to rewrite:

index/entry to index.php?entry=true

That is the easy part. I achieved that with this bit of regex in my htaccess

AddHandler php5-script .php

Options +FollowSymlinks
RewriteEngine on
RewriteRule ^index\/entry$ index.php?entry=true
RewriteRule ^index$ index.php

Now it does work but because of the slash in 'index/entry' all of my links and images etc cannot be retrieved because the page thinks it is in a different directory.

Am I missing a little bit of code in my htaccess?

Thanks in Advance,

Ben
