Tweaking visual on "Related Posts" that's incorporated into EasyBlog's individual post layout

I don't see any way to tweak the layout of the Themes, particularly I'd like to change the default image layout that's used for on "Related Posts" that's built into the individual post layout.

I think the older version of EasyBlog had an easy way to alter Themes, but I don't see any documentation or support issues related to this - specifically the Related Posts issue. (To clarify, I'm not referring to the "Related Posts" module.
