Flickr is an online photo and video hosting website operated by Yahoo. It allows you to backup & sync your photos and videos to cloud storage to access them from anywhere on any smartphone, computer or tablet. When you upload photos and videos to Flickr, it stores them into the 'Photostream'. You can sort your photos and videos in sets or collections. Flick allows you to share individual photo or video, and albums with others on your mobile devices. To learn how to share Flickr photo or video album with others on iPhone, check out the steps below.
