Align Blog Post Image to Left Side

Hello! I was wondering how to align my blog post images to the left side instead of the center on my main blog page? Once someone clicks on the post, they will see the pic in landscape mode. But for the preview (on the main blog page), I would prefer for them to see a smaller version to the left side above the title. Basically, how it is now except to the left instead of centered.
My site is https://www.sleeneys.com. I’m using the free version of Virtue and love the theme!
Thanks so much for any help that you may offer!
PS- I’m still playing with image sizes but think that 846×400 px is good. ?????
