Increasing product thumbnail size

Hi,
I'm trying to increase the product page thumbnail size, please look here: www.elandesigndev.co.nz/sapphire/index.p...silver-evening-dress
I've tried changing in the configuration in the back end and the CSS file div#hikashop_product_left_part img.hikashop_child_image but it won't change, what should I be doing?
Thanks

Hi,

As I can see, you are using cloud-zoom-gallery, so you have to add a css property for: ".cloud-zoom-gallery img{ /*property*/};"
Or edit the parameters of cloud-zoom-gallery.

Hi Xavier,

Thanks, I'm using this zoom extension: www.artetics.com/ARTools/art-zoomin
Do you know of a better one?

Hi,

No I don't really know the picture extensions.
Have you tried this property ?

.cloud-zoom-gallery img{
    height: 100px !important;
}

.zoom-tiny-image{
    height: 100px !important;
}

Thanks Xavier, that's fixed it.
Regards
Pete
