--limit 0          Maximum count of images to download per site. (0: infinite)

Full Resolution Mode

You can download full resolution image of JPG, GIF, PNG files by specifying --full true

Data Imbalance Detection

Detects data imbalance based on number of files.

When crawling ends, the message show you what directory has under 50% of average files.

I recommend you to remove those directories and re-download.

Remote crawling through SSH on your server

sudo apt-get install xvfb <- This is virtual display

sudo apt-get install screen <- This will allow you to close SSH terminal while running.

screen -S s1

Xvfb :99 -ac & DISPLAY=:99 python3 main.py

Customize

You can make your own crawler by changing collect_links.py
