Dear fellow

Maybe you would like to use s,\B/\b,,og in place of the polluted s#/(gif/\w*\.gif)#$1#g. Its more generic and will run a little faster.

The main difference between using .* and \w* in your code is that .* allways try to "eat" as many characters it can, including spaces and everything else in your way(1). In your case, it will match "gif/cart.gif is a /gif/cart" (yes, all those).

On the other hand, \w* can't match that much characters, and stops matching when it finds a space character (e.g.: one of the " ", "\n", "\t", "\f"). That way, it will match "gif/cart", because the "gif/cart.gif is a /gif/cart" have spaces before the "\.gif" that you asked your regexp to match before that.

Hope that helps.
