@Simon,
As we cannot 'stick' albums, and as people load up new albums on a very regular basis (faster than the three posters can pop their images in there), the Sony album tends not to be on the top of the album list. So we've drawn out some images from those in the Sony album, and will continue to do so on a regular basis.
The selection process is simple; we choose the photos that have received the most votes already (but have not been up on the voting pod on the Sony Experience landing page). And the ones we like the look of!
Of course, if there were more images posted into the album, there would be more images to select from...
@Woody,
These images will be changed on Tuesday, giving those who haven't checked out the channel yet a chance to vote on these images.
