I would like to get the product image fit the screen size on a mobile phone, now it is to big ( www.responsinator.com/?url=http%3A%2F%2F...39-pro-wave-8-0.html )

Configuration & Template
In the Configuration > Display > see bootstrap design = YES
template - T3BS3

What can I do to probably display the product image on mobile devices?

Please advise
Thanks

Hello,
I think that a solution can be to use Media queries through your CSS file, here is a thread where you'll find an example :

You can do the modifications in the frontend css file via the menu Configuration > Display > CSS
Use the @media tags to change the width of the columns when the width of the page is less than xx.

ex:
@media (max-width: 767px) {
.hikashop_products .row-fluid .span4 { width: 49% !important;}
}

Here is some documentation about the layout customization:
