'''Flickr''' is an online photo gallery, see [http://www.flickr.com].
Basic accounts are free, so it has become popular with people 
who like to show the pictures from their digital cameras online to friends etc.
Many bloggers use it too.
Flickr is now owned by Yahoo.

Managing the content can be done via webpages,
as well as via the ''Flickr API'', see http://www.flickr.com/services/api
