Perhaps you have used ImageShack in the past, just like me. ImageShack made some strange moves in the past few years, including removing your uploaded images. I created this tool so you can download your images and move it to a another image hosting service.
You'll need Python and Node (at least v6.4.0) to run this tool.
$ npm install
$ cp .env.example .env
$ (fill in the .env fields)
$ python imageshack_downloader.py
Unfortunately, the ImageShack API is not available anymore, so I used Puppeteer (a headless Chrome Node API) to scrape the image URL's from your ImageShack account. After that, a Python script will download all the images to the /images folder.
