Mine works out like this:
the archive page is monthly, 99 entries per page (which fits the entire month mostly)
http://www.boogie-blog.com/2005/04/
then each individual link links to the oriiginal file:
http://www.boogie-blog.com/3-brand-n...-galleries.htm
I believe that internal linking structure is important and having multiple internal links to the same page is key.
Which is also why I use the 'breadcrumbs' plugin on every page.
