Adding and linking

When I was doing my activity 9 and 10, I learned how to put pictures as a background . I also learned how to link one exercise to another exercise.
At first, I really do not know what to do. I don't undrestand the instructions. Even if I follow the instructions and try it on the computer again and again, the result that should appear on the screen doesn't appear. I also ask for help but even the person I asked for help also doesn't know what to do.
One of my classmate that is good in computer did teach me. Thanks to him I finished my activity. I also taught some of my classmates that do not know what to do.
I hope I can also share what I learned to other people.
