UK residents are far too used to Amazon Prime benefits coming to US Prime members first. So, it was no surprise, when Amazon announced unlimited photo storage for Prime members that it was only available for US customers. Well, UK Prime members need wait no more as Amazon has opened up the free unlimited photo storage service to the UK. Amazon Prime Photos allows you to upload your entire photo library via the web, using its iOS or Android apps, or using its dedicated PC app. The photos will then be viewable on your Fire TV, among other places.
