This should do what you want:

I = imread('cameraman.tif');
I2  = imresize(rgb2gray(imread('onion.png')),[size(I,1),size(I,2)]);

ImLength = size(I,1);
% Create image large enough to encapsulate both of them
Iend = uint8(zeros(2*ImLength,2*ImLength));

Iend(1:ImLength,1:ImLength) = I; % First image
Iend(ImLength+1:end,1:ImLength) = I2; % Second image

Iend(1:ImLength,ImLength+1:end) = I2; % Second image
Iend(ImLength+1:end,ImLength+1:end) = I; % First image

figure,imshow(Iend)
