How to hide frontpage "placeholder" image?

Hi,

I just updated my client's site to EasyBlog 5 and noticed that any posts without an official "cover" image are displaying a "placeholder" image on the blog's front page; see attached. Is there a way to hide the placeholder image?

Also, before the upgrade, I could click on a theme to edit certain things (Show Hits, Show Creation Date etc.) With EasyBlog 5, I can't click on the themes to edit them. Have those theme settings (Show Hits etc.) been moved elsewhere?

Thanks!
Chris
