Not sure what you mean by "save a file" but you can use imwrite to save a variable as a file:

imwrite(I3, 'Edge Image.png');

or you can save the whole figure, which would include any annotation (text, arrows, etc.), tick marks, etc. in the overlay by using export_fig(): http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions.
