Wonderful took me little breath to get it on my computer

Until now I was using MotoPress theme to build website. Very complicated and I’m still nowhere with it. Just tried Starter Templates and I see that without installing anything I have already ready website. Just replace images and wording which is very easy to do. I replaced to images and and added text to it. Now I’m plan adding to it Hotel Reservation system and will see how it works before I get more engaged.

I wonder if I could remove header images from all pages but Welcome page? Also if images are optimized or I need add to it any app? Thank you
