LUNA uses the Flickr API to allow you to search outside of LUNA. Images from the External Media Search can be viewed in the Detail View, added to the LUNA Workspace, and added to a user’s Active Media Group.
To find Flickr images in LUNA:
Images must be marked as public in Flickr.
The more tags and descriptions to an image in Flickr, the easier it will be to find them in LUNA.
Search results from Flickr will be limited to 500 images so it is important to try and refine your search.
