This is a community forum with most of the questions being answered in a timely way by volunteers or by support staff if they are more complex. This appears to be your first experience here, so a heads up that it is bad form to repost especially so soon after your first post.
I saw your first occurrence of your question and went to look at your site to see if I could help. I am on an ipad. For me your site rendered with your images the full width of your content column and looked great.
Of course I do not know how it renders on a large screen computer.
