            const { value } = [...inputRadios].find(i => i.checked === true);
            localStorage.indexChecked = value;
            imagePlaceholders.forEach((imgTag, index) => imgTag.src = images[value][index]);
        }

        inputRadios[localStorage.indexChecked||0].checked = true;
        onChange();
