The featured-article candidate Shapley-Folkman lemma would benefit from a review of its illustrations. The article has 3 supports and no opposes; the supports did not discuss the illustrations. A FA-specialist editor asked for a review of the illustrations.
There are two new images for the page, as well as an animation.

- All I can say about its illustrations is that "I am impressed". Excellent. Fleet Command (talk) 13:06, 8 October 2011 (UTC)
- Thank you, FleetCommand!
- Most of the images come from other articles, but the two best were custom-contributed by User:David Eppstein, whose image galleries awaken the "inner mathematician/artist" in each of us. :D

- Ouch! These pictures' placement really disfigure this section of talk page, at least on my screen. So, I moved them to the bottom. But in the process I noticed a problem: The alt text is very long. Remember: Alt text is a mean of accessibility. It is for those who cannot see the image and must hear it. So, alt text should not be similar to caption; otherwise, the visually-impaired people will just hear the same text twice. It is a torture for those poor folks. Make sure alt text is something like "illustration" or a short summary. Read help documentations for more info. Fleet Command (talk) 11:12, 9 October 2011 (UTC)
The Shapley–Folkman lemma is illustrated by the Minkowski addition of four sets. The point (+) in the convex hull of the Minkowski sum of the four non-convex sets (right) is the sum of four points (+) from the (left-hand) sets—two points in two non-convex sets plus two points in the convex hulls of two sets. The convex hulls are shaded pink. The original sets each have exactly two points (shown as red dots).
The article Trolley problem could use some pictures to illustrate the different variations of the problem, if anyone is interested in creating them. —Granger (talk · contribs) 19:49, 24 February 2015 (UTC)
