Subject: regular expression match and exclude

I am parsing a web page full of image links that also contain links to
the thumbnails for those images.

Here is my test data..

galleries/image1.jpg
galleries/image1thumb.jpg
galleries/image2.jpg
galleries/image2thumb.jpg
galleries/image3.jpg
galleries/image3thumb.jpg

If i use this expression..
/galleries.*(?=thumb).*jpg/

The results are just those lines containing the word thumb.

What I want to do is inverse this though and return only return that
DONT contain the word thumb.
