Hello,
What may be the problem with the following code line?
message=round(reshape(message,Mm*Nm,1)./256); using this I want to check message isn't too large to fit in cover image.
Where message=double(imread('lena.jpg')) and [Mm Nm] is the size of the message.
Thanks in advance

What does the error message say?
Double check the size of the variable message to make sure it really is Mm x Nm.
Note that you can replace reshape(message,Mm*Nm,1) with message(:)

Does 'lena.jpg' produce a third dimension for color? If so, that would account for your error message; you would have more than Mm*Nm elements in 'message'.
