Pictures Not Responsive

Hi, when i view the site on a mobile device the pictures i have on the site are not mobile optimised and therefore stick out on the right side of the page.

How do i get the pictures to display correctly on a mobile

Example is here

Many thanks

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.fullwidth a img {
width: 80%;
height: auto;
}
 
.logo a img {
width: 90%;
}

 

That worked a treat.

thanks alot
