I have pushed an updated version of my Flickr app for Windows 8.1 to the Windows Store. Flickr have switched to using secure https for 3rd party apps so I have changed the API calls to use HTTPS. You will need this new version to continue working with Flickr. Other than a couple of bug fixes you shouldn’t see any other changes to the app.
With the app you can upload a single file or multiple photos to Flickr and view your collection of Flickr photos. It will also generate HTML code for embedding photos in to a website or blog and you can share photos via email or DLNA using Play To.
The app is free from the Windows Store.
