1.) If the images are the same size you can put them in an array and save that. If different, use a cell array.
2.) You can use matfile() to create a writable .mat file, save data into it, and then load that.
matobj = matfile('c:\data\mymat','Writable',true);
matobj.image1 = randn(256,256);
matobj.image2 = randn(256,256);
loadimage1 = matobj.image1;
% or
load('mymat.mat','image1');

Hi, What can't you understand? Another thing you can do is clear everything in your workspace except the 15 images and use save to save the whole workspace (which contains only the 15 images). I recommend the matfile() approach though

Single image how? Tiled, like with the montage() function? Or stacked into a volumetric 3D image like with cat(3, .....)?

Yes, you can create an image volume. Create a 3-D array and place the images in that array.
X = zeros(256,256,15);
X(:,:,1) = image1;
X(:,:,2) = image2;
and so on
