Page does not match sample

Hello, Alexander! Thank you so much for the theme! This is really impressive. I watched hundreds of themes, but only your themes really interested me! I would like to know how you can put in the top of each page not a title, but photographs, as in your examples? And how can I insert photos without white margins on the sides? I tried to do this in the Elementor, but it didn’t work, and in programming I don’t understand anything, therefore I did not get into the code. Thank your for your time!
