The text describes sightings of the Brown Lady ghost at Raynham Hall in Norfolk, England. The information provided suggests that there is no direct mention of pictures or visual representations of the Brown Lady in the text. Instead, the narrative revolves around the ghostly sightings, the history of Lady Dorothy Walpole, and the famous photograph taken by a photographer and his assistant.

Therefore, based on the information in the text, it doesn't explicitly state what can be seen in pictures. Instead, the focus is on the ghostly sightings, the historical context, and the uncertainty surrounding the authenticity of the famous photograph of the Brown Lady.
