visual examples of painting media 

This article is very limited as to the types of paint media.  There should be a full article on oil painting, etc...  At the absolute least this page should present a visual example of all of the types of painting media.  To have two "fresco" examples and nothing for pastel, watercolor, ink, gouache, enamel, spray paint, tempera, or water miscible oil paint, is very lacking.  Providing 1-2 examples of each would improve this section greatly.  It may be a rare prose-to-image ratio spacially (i.e. more images per area than normally used) but it would help make up for the lack of extended articles, because we all know a picture is worth 1,000 words, right?
