If you need to upload photos to Flickr, this is the app to have hands down
Although BlackBerry 10 is deeply integrated with several different services such as Twitter, Dropbox, Box and Evernote, one that was not included is Flickr. To help address that concern, a new app called Share on Flickr has been released and is currently being offered in BlackBerry World for free. Share on Flickr is a very simple native app that essentially taps into the BlackBerry 10 sharing mechanism and works with the Flickr API to offer direct photo uploads to Flickr from the BlackBerry 10 photo gallery or any other app that offers simple photo sharing capabilities.
Share on Flickr is lightweight coming in at only 120kb and only requires that you login and authorize it to allow access to your Flickr account. Once logged in and authorized, any photos you share to Flickr can have a title, a description and in addition to all of that, you can also set the visibility preferences for the photo as well. You know, in case you wish to keep things private or only for friends and family.
Ultimately, there's not a lot to the app but it does exactly what it says it will do, it's native, works fantastically and best of all, it's free! If you're needing to upload photos to Flickr, this is the app to have hands down.
