Image thumbnails larger

Is there a way I can make the "homepage 2 column" and "homepage featured section" thumbnails larger?

Also, if I do not want to use all 4 featured sections, how do I remove the default icons? I already tried adding <p></p? to the image field, and that doesn't work.

 

Hello,

1. For making thumbnail larger

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

Code:

.testimonial_holder .testimonial_jcarousel img{
width:150px;
height:150px;
}
.content .feature-content img.feature-image{
max-width:100px;
max-height:100px;
} 

2. And for removing images

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

Code:

 
.content .feature-content img.feature-image{
display:none;
} 

Thanks & Regards
