Filenames...

I’ve run into a few issues with filenames. One of them isn’t entirely Windows specific, and I have an idea of what needs to be done to fix it, but no idea how to. Duplicate filenames within a thread simply overwrite any preceding files. Usually Spoiler_Image or file.png.

The other issue is Windows specific and I’ve managed to solve it at least locally by:

from django.utils.text import get_valid_filename
...snip...
                img_path = ntpath.join(directory, get_valid_filename(img))
...snip...

The issue in question, filenames like this used to make the script halt on Windows:

After importing it appears to work.

I added your call of get_valid_filename to the script and added the issue of duplicate filenames as a TODO to the README.

Oh, and there’s definitely a way to properly parse Spoiler_Image filenames since 4chanx and archive sites seem to do it, but I wouldn’t know where to start for that one.
