MATLAB: Adding multiple images together from a for loop

image processing

I am trying to adding multiple images together into one in a for loop, but seem to only display the last image. This is what I've tried. Someone please assist me.
 E = [];
 for i = 1:4
     str = int2str(i);
     str = strcat('\',str,'.jpg');
     str = strcat('C:\Users\ASUSA55V\Documents\MATLAB\images\ur3', str);
     im = imread(str);
     im = imresize(im,[64 70]);
     E = im;
     E = E+E(i);
     end
imshow(E);
Thanks

Try this out:
 E = [];
 for i = 1:4
     str = int2str(i);
     str = strcat('\',str,'.jpg');
     str = strcat('C:\Users\ASUSA55V\Documents\MATLAB\images\ur3', str);
     im = imread(str);
     im = imresize(im,[64 70]);
     E = E + im;
 end
imshow(E);
