I don't know what kind of image and how you read them, but to load in
sequence I use "for loop".
if files differ in names like file_name.1 file_name.1 file_name.3....
path_folder=3D['path/folder1/'; 'path/folder2/'; 'path/folder3/';];

for i=3D1:length(path_folder(:,1))

     for u=3D1:5
         cd(path_folder(i))
         file_name=3D['file_name.' num2str(i)];
         eval([a ' num2str(i) num2str(u)
'=3Dcommand_to_load_image(filename)'];
end
end

You can play with output of dir (or ls) command if files don't have
pattern in names.

Hope it helps
Best.

Do we really need call for this ugly EVAL?

Why not using cell or struct to store the list of things of different kinds and sizes?
