function Show_Image(loadon)
% USAGE
% Show_Image(loadon)
%
% INPUT
% loadon    if set to 1, the image file specified in StimParams.filepath
%           will be read. Otherwise, assumes that OrigFrame structure
%           already has image matrix in OrigFrame.ir, OrigFrame.red, etc.
%
% OUTPUT
% none      gui window is updated.
%
% DESCRIPTION
% Function called by AOMcontrol.m for display in gui window.
