Hi,
Please use this css into your custom css to get that look
.j2store-single-product .simple-product .span6:first-child {
display: flex;
flex-direction: row-reverse;
justify-content: flex-end;
}
.zoom .j2store-product-main-image {
margin-bottom: 10px;
width: 100%;
}
.zoomImg {
height: 900px !important;
width: 1000px !important;
}
.additional-image-list {
margin-right: 10px !important;
}
.additional-image-list li img {
margin-bottom: 10px !important;
}
Here is the custom css field
