Worked just as it said on the tin. The only bad thing is, it isn't immediately clear how you use the extension. You have to go to the lightshot gallery page, and then click on the "Download my gallery" button, which this extension adds. It's just below the drop to upload area, next to the "Screenshots history" text.
it is not obvious how to use it and it is not explained anywhere.
