last16 = 42*ones(16,1);     %set it to whatever is to go into the last 16 pixels
rebuilt = reshape([imgcopy(:); last16(:)], size(img));

Note: in your previous question, you were asking about the last 16 pixels of the last row as being removed, and the answer I provided there did that. But in your code here, you are removing the last 16 pixels of the last column, not of the last row. Rebuilding after deleting the last 16 pixels of the last row is slightly different.

rebuilt = reshape([imgcopy(:); last16(:)], fliplr(size(img))) .';

The code you have what you attached will only work if the image happens to be square.
