[filename pathname] = uigetfile('*.tif','Select An Image');
inputImages{K} = imread(fullfile(pathname, filename));

Whenever you do not know the syntax of a command, simply look at the documentation: help save and doc save.

If you have a new enough version of MATLAB, you can use matfile() to store additional array elements into an array stored in a .mat file.
You can use -append to store additional information into a .mat file, but you need to use a different variable name each time or else the existing content with that variable name will get overwritten.

Saving your first image
im1={imread('first_image')}
save yourfile im1
Adding a new image
im1=imread('news_image')
im=load('yourfile')
im1=im.im1
im1{end+1}
save yourfile im1

Have you used?
im=load('yourfile')
and when saving the first image
im1={imread('first_image')}
