NakyD on "[Theme: Virtue] How to remove grey shadows/borders around pictures?"

Hi!

I would like to have all pictures on my site without any borders/shadows/hover effects so they don't stand out from the white background. Now all pictures that I add to content area seem to have grey borders/shadows/hover effects. Could you please advice how to remove those effects? And should I create a child theme to do that?

Here's a link to my site: http://www.nakydesign.fi

Thanks a lot!
Minna
