Gallery with preview in blog

Just starting out with WordPress and Enfold and am getting confused by how to do something.

I have a blog page used to display blog posts and would like to use something like the layout here:

but with text above and (possibly) below the gallery.

I’d like it to be displayed within the same confines as my current test blog posts as shown here:
http://www.iaintaylorphotography.co.uk/blog/

ie. just a fairly simple blog post but with the gallery.

I’ve had a search through the bulletin board for similar requests but without success.

I’m using a child theme for the active ‘site’.

Are there any examples that would show me how to accomplish the layout I want?

Thanks, Iain
