I use Ubuntu 18.04
Today, I left the computer on and no one used it. And when I came back home, I saw a lot of directories, files, and images opened.
I wonder if anyone hacked into my computer?

The information you're looking for isn't there.
As you saw it open, the files was opened by your user account. There is no logging of which physical person used the computer - except for the user account logs.
Furthermore, if anyone hacked into your computer, it's highly unlikely that they would open files in this manner. Do you have for instance a cat that may have had a walk on the keyboard?
If I understand you, every attack open a new window which I can't see
