download e621 images from a list of ids

1. make sure node.js is installed
2. download/clone this repo
3. in the repo, run node index [comma separated ids file] (if no file is supplied, it will default to ids.txt)
4. wait
5. the downloads will be in e621-id-downloader/dl

To allow concurrent downloads, use concurrent.js instead of index.js. It's essentially the same thing, except it accepts these optional arguments:

• -i - The input ids file, defaults to ./ids.txt
• -o - The output directory, defaults to ./dl
• -c, --max-concurrent - The maximum allowed concurrent downloads, defaults to (and is not recommended to go above) 5
• --use-ids - Pass this argument to use post IDs as the filename instead of the md5 hash
• -s, --search - Pass a search query with this argument to download posts that match it, e.g. -s "rating:s canine"
• -l, --limit - If using -s, limit the number of posts to search for by this number, defaults to 10
