I am encrypting an image and displaying the encrypted image and also saving it in the default directory with a .jpeg extension. It displays the image fine and even reads the image using imread() but if I try to open the file that got saved I get a message that the format is not supported. Why is this happening?

I am saving the file like this -
if true
encrimage=cat(3,shuffle1red,shuffle1green,shuffle1blue);
figure, imshow(encrimage), title('Encrypted Image');
imwrite(encrimage,'eimage.jpeg','mode','lossless');
end
To open the file outside of Matlab I am double clicking on the file in the Matlab folder where it is saved.

This means, that the default application to display JPEG files on your computer cannot handle Matlab's 'lossless' JPEG format. We do not know which application you have installed, but the solution is to use another one.
