    The PlaceImageModel is a read-only model used to fetch images related to a Place.  The model
    performs fetches incrmentally.  The number of images which are fetched at a time
    is specified by the batchSize property.  The total number of images available can be
    accessed via the totalCount property and the number of fetched images via the count
    property.

    \table
        \header
            \o Role
