Licensing and technical audit;
Remember that the aim of the contest is to promote the creation of Free and Libre content, and ship as many as will fit to as many people as possible!

Three of the images in the shortlist (and two in the .zip) are not CC-BY-SA and so can't be shiped, as only free/libre images are eligable for inclusion (all images offered _must_ to be licensed as CC-BY, CC-BY-SA or CC0 to be considered). Currently this rules *out* shipping of the following three as we can't do so legally:

  Forbidden City by pixelflake (wrong licence)
  White Pigeons by noombox (wrong licence)
  Yellow Flower by Angela Henderson (wrong licence)

Andrea Cimitan did an initial preview test of the remaining images checking for theming/desktop interactions. A couple of the images highlight issues with the present average-highlight colour algorithm in Unity/Unity-2D. Either the images or code may tweaking.

Cut-offs. The following exhibits an issue with the person's head being cut off by the top menu bar on all 16:9 widescreen displays (now the common-case). This may be solvable by cropping a slice off the bottom to give a wider aspect, and effectively moving crop from the default centre:

Jumping Man by Marcus Møller (re-cropping)

Dark/unsaturated: The following has very low histogram spread with everything pretty in the bottom 20th-percentile:

White Flower by Zuphi (low saturation/histogram)

There images with high-frequency noise tend to have compression issues—we only have a limited space budget on the CD and can't blow it on just a single image, because we have to maximise the number shipped. This particularly affects:

The Brew by Fernando Garcia

(but we'll see what fits as trying various combinations of recompression).

Question:

Iain and the shortlist team; have you picked any illustrations for shortlisting aswell? There's traditionally been an illustrated animal-of-the-release in the pool too a la the Pangolin at the top of:

I'm asking as in the packaging code we have a separate codepath to manage illustrations, to that for photographs (as they compress differently).
