无法在路线之间导航。VueJS

我正在制作一个画廊，并且已经能够显示所有这样的照片：

当我单击按钮时，图像将显示给用户：

当我尝试转到下一张图片（路线）时，它什么都没有！但是，当我单击上一个按钮时，转到上一个图像，然后返回画廊

这是我的路线：

  const routes = [
  {
    path: '/',
    name: 'Home',
    component: () => import(/* webpackChunkName: "home" */ '../views/Home.vue')
  },
  {
    path: '/about',
    name: 'About',
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
  },
  {
    path: '/gallery',
    name: 'Gallery',
    component: () => import(/* webpackChunkName: "gallery" */ '../views/Gallery.vue')
  },
  {
    path: '/gallery/photo/:img',
    name: 'Photo',
    component: () => import(/* webpackChunkName: "photo" */ '../views/Photo.vue')
  }
]

这是我的照片组件，在其中显示所选图像：

    <template>
  <div>
    <img v-bind:src="img" alt="imagen" />
    <br />
    <button @click="previous()">Anterior</button>
    <button @click="next()" style="margin-left: 10px">Siguiente</button>
  </div>
</template>

<script>
export default {
  name: "Photo",

  computed: {
    img: function () {
      const url = this.$route.params.img;

      return url.replaceAll("%2F", "/").replaceAll("%3F", "?");
    },
  },

  methods: {
    previous: function () {
      this.$router.go(-1);
    },

    next: function () {
      this.$router.go(1);
    },
  },
};
</script>

这是我的照片组件，其中显示所有图像，用户可以选择其中之一：

<template>
  <div id="gallery">
    <div id="photo" v-for="(img, index) in photos" alt="img" :key="index">
      <img v-bind:src="img" /><br />
      <router-link :to="{ name: 'Photo', params: { img: img } }">
        <button>Visitar</button>
      </router-link>
    </div>
  </div>
</template>

<script>
export default {
  name: "Photos",

编辑

我有两种导航方法，但是我认为这是错误的...
