Simple script to concurrently grab full-page screenshots of websites and save them follows:
* `perceptual_hash-given_file_name.jpg`
* `perceptual_hash-given_file_name-thumb.jpg`
Where the perceptual hash is the pHash of the image and the thumb is, well, the thumbnail of the image north-cropped to 128px by 128px.
$ git clone <this repo>
$ cd fgrab/
$ npm i
$ echo "filename.jpg http://maggi.cc | node index.js --base /tmp/"
Just feed it a list of filename url pairs and it'll do the job.
$ cat file_url.list | node index.js --base /tmp/ --procs 5 --force
Just set the USER and PASS environment vairables to the username and passwords required by the site that you're grabbing. Sorry, I needed to grab multiple pages from the same site, so no support for per-site credentials.
