Problem in Widget area

I need to have someone look at a problem I'm facing regarding the widget bar. Pls have a look on www.tvkinstructie.nl and click through to any page. Any picture I am adding to the widget area appears extremely large, no matter which size I choose. I'd be grateful if you can help me solve this problem.

 

Hello,
Please paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.

Code:

.sidebar img {
max-width: 100%;
width: auto;
}

While adding widgets in some widgets you can set its height and width.
Thanks & Regards
Pramod

 

This worked beautifully, thanks.
