How can I smoothly switch between images?

Hello

I'm working on an experimental set-up that requires the smooth switching of images. For example image 1 is of a table lamp with the light OFF and image 2 is of the same table lamp with the light ON (same size and from the same angle). I would like to switch these images so it appears that the table lamp turns ON and OFF. So image 1 is displayed for 5 seconds and then is switched with image 2. Thanks.

ImOn = ones(100, 'logical');   %For you, imread('lamp_on.png');
ImOff = zeros(100, 'logical'); %For you, imread('lamp_off.png');
Ion = imshow(ImOn);
hold on
Ioff = imshow(ImOff);
Ioff.Visible = 'off';
hold off

for j = 1:10
    if strcmpi(Ion.Visible, 'on')
        Ion.Visible = 'off';
        Ioff.Visible = 'on';
    else
        Ion.Visible = 'on';
        Ioff.Visible = 'off';
    end
    pause(5);
end
