I looked the image used to illustrate [[Miniskirt]] is not Featured Picture quality: it fails to capture the edginess or the sexiness that this garment evokes in the popular imagination. However, it does the job by illustrating what a miniskirt looks like -- & it is a free image.
Sexiness is considered by many to be utterly intolerable. See the "discussion" about the (professional, high-quality) picture that Bomis licensed GFDL for our use in the [[Bikini]] article. It was lynched explicitly /because/ it was a good picture. The attractiveness of the model was the stated reason for deleting it.
