function myimagemenu(figure_handle)
%IMAGEMENU adds a context menu to change image properties
%   IMAGEMENU(handle) creates a context menu for all images with the parent
%   handle that allows image properties to be easily changed.
%   IMAGEMENU, without any input arguments, will create this context menu
%   for all images that are found in the current figure.
%   This allows users to easily change image properties, and is especially
%   useful for compiled programs, as users do not have access to MATLAB's
%   property editor.
