Increase image size | WordPress.org

My apologies a similar question has been treated 1.5y ago, here’s some code to do just that:

.wpclv-attributes .wpclv-terms .wpclv-term {
    width: 60px;
    height: auto;
    line-height: 1;
}

.wpclv-attributes .wpclv-terms .wpclv-term-image span, .wpclv-attributes .wpclv-terms .wpclv-term-image a {
    width: 100%;
    height: auto;
    line-height: 1;
}

.wpclv-attributes .wpclv-terms .wpclv-term-image img {
    display: block;
}
