I was correct, there is a file hidden inside the picture. I tried to open it with 7-Zip, but it asks for a password. Maybe the password is inside the picture?
how do you open that !?
rename jpg to 7z
Nah, it will say file corrupted (at least for me and someone). The way to open it is to leave it as a .jpg and use "Open with" to open it with 7Zip (or whatever you use).
