You may change or add some special effects onto your pictures.
For mine, I wanted to show that my character is angry, so:
I clicked at the top "Insert"
and clicked on "shapes"
I found what I wanted to put on my picture to make my character look like she was angry.
I had to copy and paste the same shape onto at least 4 more pictures (I did from #149-160) so that people can see it.
If you copy and paste the shape onto your picture, it will stay at the same place.
