how to save multiple(M-by-N-by-P) images..?

Can anyone please help me how to store multiple (M-by-N-by-P)images in a single variable. Im trying with variable_name(:,:,:,i)where i indicates diff image, but this is giving error.

Please post the code and the complete error message. Otherwise we can guess only, and this is usually more confusing than helpful.

Are they color images? It looks like it because you're trying to stuff images into a 4D array.
