This is a nodejs script that requires the nightmare npm module. https://www.npmjs.com/package/nightmare
In the file facebook.js you will find a lot of cryptic text. That's because i have encrypted my password and username in another file named fapx.txt and I am decrytping that file here using a key which is that cryptic text. You won't find that file here ;).
In case you want to directly run the script use Facebook_simple.js(remember to put your own username and password).
You cannot run this script on a cloud hosted IDE and make use of their superfast internet connection to load all the Images at once. BEACUSE facebook won't allow you to login from a different computer(in some other country). Unless you find a way to open up facebook on the hosted computer and remove the temporary lockdown. Good Luck!
