I was wrong...

>This seems to work:
>>rewrite ^/e/(.*) /$1 permanent;

It only works for the first level...
'threedaystubble.com/Gallery.html' works but other links from that page that got deeper into the file structure do not!

So, maybe map directive is needed after all...

I'm planing to try that next, but I want to make sure that a more simple 'return' redirect won't work in my case.
