Publishing to the Web
Through the use of plugins, Shotwell can publish photos and videos to the following services, each of which requires an account:
To publish selected photos in a collection, choose Edit ▸ Preferences and click on the Plugins tab to enable the plugin for the service you want to publish to. Next, choose, File ▸ Publish, press the Publish toolbar button or use Ctrl+Shift+P. You will see a dialog that lets you select a publishing service. You will then need to log in or create an account.
Similarly, publishing to Flickr, YouTube or Google Photos requires you to log in and permit Shotwell Connect to access your account.
