[jpegFiles,pathname,FilterIndex]=uigetfile({'*.png'},'Select sequence of images','MultiSelect','on');
N=length(jpegFiles);
imageArray=cell(1,N);
grayimage = cell(1,N);
filtArray=cell(1,N);
sizeimage=cell(1,N);

for i = 1:N
imageArray{i} = imread((fullfile(pathname,jpegFiles{i})));
figure(1);
subplot(4,3,i);
imshow(imageArray{i}); % Display image.
str=sprintf('original image %d',i);
title(str);
end
for j=1:N

It asks the user to select some images. It reads the images and displays them in color in one figure. It then goes back over the images and makes a grayscale version of each and displays the grayscale version in a second figure.
