How to convert 8 Binary images of size 256 x 256 into a Grayscale image of same size, i.e., 256 x 256?

Suppose, I have 8 Binary images of same size. Then, I want to combine binary bits of all 8 images pixel-wise to form 'a' 8-bit depth Grayscale image of size, same as Binary images.

The images are attached herewith in 'zip folder'.

Already your images are in gray scale right? What exactly you expect?

I have updated the images. Now, these are in Binary.

images = dir('*.tiff'); 

N = length(images) ; 
iwant = cell(N,1) ; 
for i = 1:N
    iwant{i} = imread(images(i).name) ;    
end
I = cat(3,iwant{:}) ;

Use bitset(). If you can't figure it out, write back. Some demos to help are attached.
