Best Answer

image_name = {'first' 'second' 'third' 'fourth'};  % give names with extension
I1 = imread(image_name{1}) ;  % read first image 
for i = 2:4   % loop for rest of images 
    I2 = imread(image_name{i}) ; % read i'th image 
    I12 = I2-I1 ;               % substract
    % do what you want 
end
