Yet another lame image dumper

And here's yet another lame script for dumping images off 4chan.. Since we probably don't have enough of them already.

Made it over the weekend.. Why?
Well, first of all, I was bored.
Second, all other I could find kinda sucked
Third.. I love python, and if its not made in python, its useless :D

Command line script, tested on linux and windows.

Feedback wanted. Good feedback especially wanted.

True, the fetcher is still rather stupid. It could f.x check if the last image displayed in a thread on the index already exist on the disk before requesting a full thread dump,

and it doesn't handle other than the main page of index (not page 1, 2, 3 and so on). The last part is just laziness by me, tho.

And the Content-Length part is a very good idea, thanks :) Does 4chan server give HEAD? Will look into that when I get home.

Stil adding some small features here and there (added a "minimum images" limit option for when threads should be downloaded - this could also be done way smarter), and refactoring / restructuring code to make it easier to read and work with.

Hmm.. Your content-length idea could be combined with "only if image is less than or bigger than X size" options.

Any more ideas for simple functions and features to put in? Or better ways to structure the code?
