How do you browse / ‍ ‍ ‍ /?

For personal reasons, I do not browse /prog/ from my computer. (I also have not net connection much of the time.)  To look at page I send mail to a demon which runs wget and mails the page back to me. It is very efficient use of my time, but it is slow in real time.

How do I prevent wget from checking http://boards.4chan.org/b/ and http://boards.4chan.org/a/ when I just want to download the jpegs of a single thread? excluding directorys didn't work somehow. Or do I have to extract the picture URLs from the thread with an other program?
