Strange. Did you see the example in the help where it talks about clipping and how to specify a different output class?

Otherwise if you don't want to use imadd(), you can use + if you just cast to double or uint16:

output = double(image1) + double(image2) + double(image3) + double(image4) + double(image5);

gives error "Matrix dimensions must agree."

The images must be the same size of course. If you still want to do it, then you must use imresize() to force one image to be the size of the other image.
