help with permanent Redirect in .htaccess file

Question

I'm using plogger with wordpress and I'm in the process of moving current photos to new directories. I need to setup a permanent redirect once I change the directory

For example.

Current location: www.mysite.com/products/cakes/birthday/batman-cake.html

New location: www.mysite.com/products/cakes/superhero/batman-cake.html

So if someone types in the current location it should redirect to the new location.

I have 2 .htaccess files. One in the root directory and one in the Plogger directory. the plogger one I assume is used to make the urls pretty and I think this is where I need to make the changes. Also I only want to redirect individual pages and not the entire directory

See the plogger .htaccess below.

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteBase /products
  RewriteCond %{REQUEST_URI} !(\.|/$)
  RewriteRule ^.*$ http://www.mysite.com%{REQUEST_URI}/ [R=301,L]
  RewriteCond %{HTTP_HOST} !^www [NC]
  RewriteRule ^(.*)$ http://www.mysite.com/products/$1 [R=301,L]
  RewriteCond %{REQUEST_FILENAME} -d [OR]
  RewriteCond %{REQUEST_FILENAME} -f
  RewriteRule ^.*$ - [S=2]
  RewriteRule feed/$ plog-rss.php?path=%{REQUEST_URI} [L]
  RewriteRule ^.*$ index.php?path=%{REQUEST_URI} [L]
</IfModule>

Please note that someone set this up for me a while ago and I'm not a programmer but I'm a little technical.

Any help would be appreciated.

Thanks
