Answer 1

%create a directory
tdir = tempname();
mkdir(tdir);
numimg = 10;
imagenames = cell(numimg, 1);
%store some images in there
for K = 1 : numimg
  randimg = randi([0 255], 32, 32, 3);
  imgnames{K} = fullfile( tdir, sprintf('image_%03d.png', K) );
  imwrite(randimg, imgnames{K});
end
pause(20);   %"later"
%read that folder
images = cell(numimg, 1);
for K = 1 : numimg
  imgname = imagenames{K};
  if ~exist(imgname, 'file')
    fprintf('somehow a file went missing: "%s"\n', imgname);
    images{K} = [];
  else
    images{K} = imread(imgname);
  end
end
%subplot all of them in one figure without overlapping
image4 = cat(4, images{:});
montage(image4);

Note:

If your only reason for reading them back in is to display them, then you can skip from "read that folder" onwards and instead use just

montage(imagenames);
