    export default {
       data() {
         return {
           savePhoto: new Boolean(window.localStorage.savePhoto) || false,
         }
       },
       methods: {
         savePhotoFun(value) {
           this.savePhoto = value;
           window.localStorage.setItem('savePhoto', value);
         }
