Image won't align right in 20-10 theme

HI,

The home page of my site has one image on the left, with the intro text wrapping next to it on the right. I’m trying to use another image on the right hand side. I’ve chosen ‘align right’ but it wraps itself around the text and won’t go all the way to the right.

I wonder if this is because it would go into the ‘widgets area there? (although I have disabled them except for the search button).

I thought maybe creating a new class within a <div> tag would force it to go into the widget area but not sure how…

Any suggestions? many thanks,
