There is an updated version of my Flickr Upload app for Windows 8.1 in the Windows Store. The app has a new multi-photo upload features where you can select multiple photos and upload them in one go. You can pick photos from the local drive, SkyDrive or the Network and the app will go away and upload them for you, notifying you when the upload is complete.
In the last update I added a gallery view so you can see your collection uploaded Flickr photos and you can view an individual photo to view its metadata and embed codes. So this Christmas take plenty of photos and use my app to uploaded them to Flickr from Windows 8.1.
If you use Flickr and have a Windows 8.1 device this is the easiest way to upload and view your Flickr photos. The app is free from the Windows Store, if you use the app please let me know how you get on with it.
