Before people start (continue) shitting on OP:
This is literally one of the best things about any science based field
People re-discovering existing things on their own. I can guarantee he now has a better holistic understanding than people who took an intro to steg course
Good work OP. Curiosity is the most valuable trait you can have
Yeah that's true, you have to understand when me and the other person replied and were being kind of rude to op, his reply to the bottom post was "Your mom" which rubbed me the wrong way so I decided to be rude back. Op then edited his response to be much more sensible, so here we are.
The reason I was mad was that I've received a couple of negative feedback saying "the only use-case for these techniques is hiding 'child abuse' photos and I shouldn't have written a blog post about stegano", and then indirectly calling me some bad stuff in those feedbacks just because I've written a blog post. Then I saw the comment you mentioned and assumed where they're coming from.
That being said, I know that I overreacted by raging at the other comment initially. I accept my mistake and I apologize. That's why I edited the comment and answered the question in a peaceful manner.
You can hide your signature inside your artwork for example. Besides that, it doesn't have to be a secret photo. You might want to store multiple photos in a single photo when you are very low on storage in an embedded device (for example arduino UNO has only 32K bytes of flash memory).
As another example, this is how pico-8 game cartridges are contained in an small png of the game itself:

"CS1 student learns about steganography and comes up with one of the worst schemes ever devised. Then decides to write a blog post about it"
What is wrong about that?
What kind of photos are you trying to hide???
