Article intro image width problem

Hello,

in the category blog page article intro images do not have stndard size and they are showing their full size as you can see in here miko12.bg/bg/products/chocolate-line .
I would like to make them responsive and add a width :100 % ; but i do not know where.

Thanks in advance.

How did you set them in article editor. Your site requires login so we can not look

i imported them to intro image in images and links. i also enabled the site so you can see it ivan thank you,

Add this to template_css.css:

.item-image IMG{
width:100%
height:auto;
}

i did it but nothing changed.

yea it is ok. you forgot a ;

.item-image IMG{
width:100%;
height:auto;
}

thanks again ivan
