Have a read here and here. It will greatly improve your chances of getting an answer.

Also, with any size image that is not tiny, it will probably be a bit tricky to put everything together in one file.

Files = dir('./Images');  % Your images are saved in Images folder in current directory

for i=3:length(Files)     % Loop starting from 3 to ignore . and .. generated from above in Files
     
    imgFile = Files(i).name;
    img = imread(imgFile);
    save(string(imgFile(1:end-5)) + '.mat','img')    % Saving files in current directory

end

And if you cannot be sure, that the extension is '.jpeg' in all cases:

Files = dir('./Images');   % Your images are saved in Images folder in current directory
Files([File.isdir]) = [];  % It is not documented, that . and .. are the 1st two elements
for k = 1:numel(Files)     % Loop starting from 3 to ignore . and .. generated from above in Files
    imgFile = Files(i).name;
    [~, imgName] = fileparts(imgFile);
    img     = imread(imgFile);
    save([imgName, '.mat'], 'img');    % Saving fileas MAT in current directory
end
