My phone photos are 2.2 MB each. 1,000 GB's is 1M MB's which equates to approximately 450,000 photos. At $18.99/TB/year, 1,000 photos would cost ~$0.42 a year.
Photos can easily be 30 MB each or more, especially from dedicated cameras. If all photos were 30 MB it would cost $5.69 per year for 1,000 photos.
Not making any point, just calculated it for myself and thought to share.
