6. Dropbox
Dropbox is one of the best online photo storage services because you can easily upload and save photos from your smartphone regardless whether it is working on Android or iOS. Also, you can upload photos from your computer just as easily, and you can share them with other Dropbox users. There is no tagging and printing like most of the photo storage services, but it is ideal for photographers and people who want to store their photos permanently. You can use 2GB of this photo storage service for free, or you can expand your storage up to 100GB for $9.99 a month.
