 Hurray !

Now I found a solution for the image gallery section:
I just added this code: 
<div class="page-width">
to the top of the "image-bar.liquid file"
It look s perfect but get this error message in shopify admin: ???

HTML error found

Broken HTML has been detected in your theme’s image-bar.liquidfile. Check that there are no missing or extra HTML tags present.

If you haven’t made changes to this code, contact support for help resolving the issue.

Just needed to add a closing div tag to the end then this is solved!

Can you please explain in detail how you avoided the html error? 

You said you added a ">" at the end. Which end do you mean, where?

Thank you very much
