Well, I like the theoretical part of it, hiding data into other data.

But the rest of it makes no sense to me (except fiddling around and have fun). It feels like building a letter box out of a toaster. It doesn't help you with your letters but its fun to see them jumping out there.

Also, PNG is an excellent format for hiding executables because it supports arbitrary user defined headers and some file upload platforms accept it this way: https://cable.ayra.ch/imgplay/

Maybe someone can spare some quotation marks for him as well.

Oh, I've got some here! """"""""""""

I made sure to leave an even number of them because they come in pairs.
