+ \subsubsection{Images}
+ 
+ Bitmap/Pixelmap images can be created through the subclasses of
+ \class{Tkinter.Image}:
+ 
+ \begin{itemize}
+ \item  \class{BitmapImage} can be used for X11 bitmap data.
+ \item  \class{PhotoImage} can be used for GIF and PPM/PGM color bitmaps.
+ \end{itemize}
+ 
+ Either type of image is created through either the \code{file} or the
+ \code{data} option (other options are available as well).
+ 
+ The image object can then be used whereever an \code{image} option is
+ supported by some widget (e.g. labels, buttons, menus). In these
+ cases, Tk will not keep a reference to the image. When the last Python
+ reference to the image object is deleted, the image data is deleted as
+ well, and Tk will display an empty box wheerever the image was used.
