Hi
Thank you for your answers.
When I change the headers the first image index_01.png becomes no visible, so I had to return back as the previous headers to show it all.
I´m aware I have still to learn, and substitute the images with text.
But still, with the "description", the "Title" above, and the "title=" and "alt=" I have managed to get my sites to rank on 1st Goole pages.
