// 1. Open an image in the full screen photo viewer mode. (Media -> Photos -> Click last pic)
// 2. Click on the download button on the open photo to trigger the process.
// Script goes back pic by pic and downloads each one. 
// Config values:
// --> If you need to stop in the middle just enter `handBrake = true` in the console.
// --> Set the till value to something smaller than the total number of pics.
// -----> ie: `var till = 200` will make it download all pics from last one to 200.
var till = 170;
