Hi

By default the theme doesn’t have an option to increase thumbs size but you can use custom css to achieve that: http://screencast.com/t/mb6h468Uqd

@media (min-width: 1023px) {
.page-id-121241 .td_block_16 .td_module_mx4 {
width: 198px!important;
}
.page-id-121241 .td-block-span4{
padding-left: 5px;
}
}

Thanks!
