Downloads whole img content of a board
Dir is created @ script location
Excludes already downloaded files so it's able to update a library (executed by cron maybe?)
Set by default on /wg/ board
Script is now able to download a specified thread or threads from set board:
get_img.py -b <board> -t <threads IDs>
so by running:
> python get_img.py -b wg -t 7356456,3546345
You will fetch 2 threads from /wg/
