I say Sander's work was more typology than portraiture. Typology is more documentary. He was trying to document a society at a particular time rather than to tell us about an individual or group. A "portrait" of a society, some might say, but I would say it's closer to a "study" of all the types that made up that society. In doing this at first, he inadvertently made a social statement that he soon realized would get him in big trouble. Later he realized that his documentary project ran deeper than the straight documentation he had originally set out to do. It was a big deal at that time to show people from all classes of society in the same manner, on the same level, without placing one over or under the other, without ignoring certain classes, and to do it as objectively as possible. Soldiers, farmers, homosexuals, factory workers, tradespeople, gypsies, homeless people, you name it, presented alongside the higher-class folks. Just cuz the subject is a person doesn't necessarily mean it is portraiture, IMO. The work is genius, but I don't hold it as inspiration for "portraiture". Definitely for other things, though.
To insert an image, you can type in the HTML, I believe. There is also a "mountain" icon above the text cell. You click it and then are prompted to paste the location of the pic...but copy the address of the pic first, because once that pop-up window comes up, you can't do anything else.
