Do try to scan at the highest resolution possible; you never know what you will see in the picture.  My husband scanned a picture of a building that was included in the family album.  Imagine our surprise when we saw on an upper floor balcony my great grandmother and some of my father's aunts and uncles.  This was not visible in the printed photograph.  We concluded this was the apartment building in which they resided.
