Back a few weeks ago when I posted about being able to download your photos from flickr & google, because I am a little wary of the “One place for all your photos claims”. I struggled to find a decent way to bulk download photos from google photos. Well there is a way to bulk download everything from google, via there take out service.This is a feature where you can download ALL the data stored in various google service. You must log in with your goggle account and can then select the data set you want, in the case of photos they are downloaded in zip format. If you read the learn more link you can download to google drive or drop box of even via email.
Having such a data “take out” facility makes me a less apprehensive about storing things on google services.
