Some problems to Forever Theme

Hello,
I installed and try to customize Forever Theme.

This is the URL that i’m doing my development:
https://www.elpanaderocasero.com/?theme=forever-child

But i have got some problems:

1. In home page i can’t see the image from the post, for exemple, i want to show the image above the title (Molletes, Pan de leche de almendra, …) and i don’t know how.

2. I want to put and slider with photos down the title page like this:
https://quesoparem.org/

Can anyhone help me?

Thanks a lot
