When comparing OneDrive vs Flickr, the Slant community recommends Flickr for most people. In the question“What is the best cross-platform photo backup and viewer service?” Flickr is ranked 3rd while OneDrive is ranked 4th. The most important reason people chose Flickr is:
Flickr has an app on Windows, OSX, iOS and Android, called Flickr Uploadr (available for download in the [tools](https://www.flickr.com/tools/) section) that can automatically upload images to Flickr. It can even pull images from external drives and other cloud storage services such as iCloud.
