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
