Linden Lab have recently found themselves in a user permissions pickle over their use of pictures for their pic of the day blog posts. Wizard Gynoid pointed this out to me in a recent comment, whereby Whiskey Monday surprisingly found that her picture had been used.
The main issue is a lack of communication, nobody from Linden Lab told Whiskey that her picture had been selected. Photos submitted to the Second Life group pool on flickr were being used on sites such as Facebook, Tumblr and Google +, no matter which rights had been selected by the author on flickr. There are two problems here, one is ignoring permissions but probably the larger issue is not informing the author. Most people would be happy to allow Linden Lab to use their photos for promotional purposes, as long as there’s attribution and communication.
