Text and images are both represented as arrays of bytes. You can reshape those arrays into vectors. Now you have an array of bytes to be hidden and the hiding algorithm does not care where the bytes came from.

For example, if the vector value is 67, it does not matter to the hiding code if that is a grayscale level of an image, or if it is the green component of an image, or if it is the letter 'C': the hiding code just has to know that 67 is binary 01000011
