You would have to create an Array containing the responses you want to send. Then, you can use Math.random to get a random number between 0 and 1 (1 inclusive) and Math.floor to get the index ranging from 0 to arrayLength - 1.

const Responses = [
    "image 1",
    "image 2",
    "image 3",
    "image 4",
    "image 5"
];

const Response = Math.floor(Math.random() * Responses.length);

console.log(Responses[Response])

client.on("message", message => {
    if (message.author.bot) return false;
    if (!message.guild) return false;
    if (message.content.indexOf(Prefix) !== 0) return false;

    const arguments = message.content.slice(Prefix.length).split(/ +/g); // Splitting the message.content into an Array with the arguments.
    // Input --> !test hello
    // Output --> ["test", "hello"]

    const command = arguments.shift().toLowerCase();
    // Removing the first element from arguments since it's the command, and storing it in a variable.

    if (command == "random") {
        const Response = Math.floor(Math.random() * Responses.length);
        message.channel.send(`Here is your random response: ${Responses[Response]}`);
    };
});
