Add text to .jpg / png / gif

I heard that there is a way to add additional hidden text inside the image file code (e.g. jpg / png / gif).

If we open this image in the windows, the image will be shown, but if we open it with some text editor (for example, notepad ++), we will see our hidden text.

What is the name of this method? What can you say about this?

Thank.

Look at steganography. There are many tools to add any hidden data that you want there. Usually, although it is not readable in a notebook. you need a companion tool for the one you used to add data in the first place. Using this, you can even hide the binary inside.

copy /B img.jpg + some.txt

Thus, both files will be merged into img.jpg file. Text from some.txt is appended to the end of the img.jpg file.
