title: var rand image without repeating
body: <p>I wish I wouldn't repeat the images until I send all the photos possible, is there a way?</p>
  <pre><code>const discord = require('discord.js');
  const image = require('../image.json')
  var rand = image[Math.floor(Math.random() * image.length)];
  exports.run = async (client, message, args) =&gt; {
  
           const embed = new Discord.MessageEmbed()
          .setColor('RED')
          .setDescription(`Dog`)
          .setImage(rand)
           await message.channel.send(embed);
  }
  </code></pre>
