    Question steganography image problem

    i encountered a program that uses steganography. now the image being modified ( behind which a text message is hidden) is saved on my desktop. the image when opened appears exactly the same as my original image but its thumbnail appears totally different filled with different colors over the image. what to do ?
    also is it ok for a project on steganography that modified image looks exactly the same as original limage or should it change a little bit?

    It must look indistinguishable from the original. This is used for encryption of information without others knowing that this is occurring. If you change the image's appearance, you've hung up a huge red flag.

    My guess is that it's due to a poor implementation of steganography.
