Specifying a Basic Picture
A picture can be inserted into a presentation slide by use of the picture element, <pic>, which is similar to the shape element but contains some key differences that enable more complete storage of picture information. This basic picture element should contain a <blipfill> and some basic non-visual picture properties.
