Auto flickr image handling replace '_b' issue

In the file lightbox2/js/auto_image_handling.js the line href = $(child).attr("src").replace("_s", "").replace("_t", "").replace("_m", "").replace("_b", ""); is replacing the wrong when the url is something like: http://farm4.static.flickr.com/3150/2685270761_b48bfdb6c8.jpg.

I fixed it on my installation with the code: href = $(child).attr("src").replace("_s.", ".").replace("_t.", ".").replace("_m.", ".").replace("_b.", ".");
