[Plugin: CDN Rewrites] [CDN Rewrite] not working

HI, as I can see in the forum, some people stated [CDN Rewrite] plugin is not working, I found poor documentaion and it looks like the developer is not answering questions in this forum,
I’m unable to make it to work correctly, as well. Wen on debug mode, it writes down to my page the correct redirections, but removing the debug mode I can’t see any rewrite to my subdomain, nor can be seen by Google’s Mozilla plugin, so I asume i’ts not working at all. Despite I’m not sure about this because i’m not sure neither if my httaccess script is correctly writen. I tried to set up differnt configurations but haven’t succeed yet.
my server structure is as follows:
/root folder/
/web/ #wordpress install
/images1/wp-content/uploads/… #same structure as wp-content w files for subdomain (1)
/images2/ #subdomain (2)

On my root folder I tryed to make httaccess redirects to my subdomain(s):

#Options +FollowSymLinks
RewriteEngine On

Rewriterule ?mages1/ - [L]
Rewritecond %{REQUEST_URI}!(^/images1/.*$) [NC] 

Rewriterule ?mages2/ - [L]
Rewritecond %{REQUEST_URI}!(^/images2/.*$) [NC]

I’m trying to set up post images in to subdomain images1 to make download balance.
I use subdomain images2 for custom field images on my pots wich by the way work fine since I make a direct call to the image url as: https://images2.femweb.info/recortar.png
On the other side, post images using urls as:
src=www.femweb.info/wp-content/uploads/2010/01/image.png
dont get rewriten either by the abobe code, or the CDN plugin. Images inserted as:
src=wp-content/uploads/2010/01/image.png
had erratical behaivor with the above code but didn’t work fine with the plugin
Does anybody know what I’m doing wrong or give a clue on how to do this?

thanks in advance
PS I guess my shared hosting has PHP 5.x and Apache 2.x
