If I understand the problem correctly, you could try two things:
Redirect requests to /(anything)/images/ to /images/ when the directory doesn't exist:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule [^/]+/images(/.*)? /images$1
Use absolute URI's in your HTML:
<img src="/images/abc.gif">
