There was some discussion in chat and in the comments on this question about the choice of example images. Initially the images were criticised for being exclusively of women. The image of Lena Söderberg also had its origin highlighted. The question has since been edited to replace this image with some peppers, which addresses the second issue.
Personally I don't see any problem with the 3 example images being all men, or all women. What stands out to me is that they were all female models. If they were a female scientist, a female bank robber, and a female politician, then I doubt the conversation would have started.
I'd like to see an indication of the community's feelings about how to approach choosing example images, in order to help avoid unintentional stereotyping or exclusion (I believe we already have a community that would deal with intentional problems with downvoting).
To avert edit wars, the name is pronounced "Lenna" but spelt "Lena"
