How to add an header image on the homepage

No, nothing is changed.
I don't want to install another plugin and spend other time to learn how to use it, I prefer to do the most I can by the theme settings. And as I see it seems not possible, probably next days I will ask a refund.

Thanks

No problem - if you need my help with anything just let me know.

Well, in the end everything is fixed now, the chat we had by facebook was faster then the forum here, so it has been easier to solve the issue.
Also I realized that using some online tools for the view from mobile (like http://mobiletest.me/ ) often it give not real results, testing directly from a real mobile it's much better and this time it gave me a different (real) result.

Thanks for the great support!
