Linear operation on images

Hey people, I'm trying to add multiple frames to form a single image using the linear operation on images in Matlab. How can I use the "for loop" to add these frames by generally specifying the file names?

Try this (untested);

counter = 0;
for f = 1 : numberOfFrames
  % Get the filename of the next image (somehow).
  fullFileName = GetFileName(f);  % You write this, of course.
  if exist(fullFileName, 'file')
    imageArray = imread(fullFileName);
    if f == 1
      sumImage = single(imageArray);
    else
      [rowsS columnsS numColorChannelsS] = size(sumImage);
      [rowsF columnsF numColorChannelsF] = size(imageArray);
      if rowsS == rowsF && columnsS == columnsF && numColorChannelsS == numColorChannelsF
        % Sizes match -- it's okay to sum it.
        sumImage = sumImage + single(imageArray);
      else
        % Sizes don't match.  Skip it.
        uiwait(msgbox('Sizes don't match'));
        continue;
      end
    end
    counter = counter + 1;
  else
    continue; % Image doesn't exist.
  end
end
meanImage = sumImage ./ counter;
imshow(meanImage);

If I were to have frames from 1 to 100 ,how do I feed them all at once into Matlab?
