Discord.js | How do I make my bot send a random image?

Question

I have tried a bunch of things that I've seen and none of them seem to be working for me. I am using the thing where when you do a command it activates a file in the commands folder, and most of the other scripts dont use that.

Without seeing any code, it is quite difficult to point you in the right direction. It would help more to define the issue you are having (actual errors and/or functionality) along with seeing the code you are using. The solution also depends on where the images are coming from.

Assuming your images are in a local folder, here is a basic example:

if (message.content === '!random') {
    // get a random index between 0 and length
    const idx = (len) => Math.floor(Math.random() * (len));

    // get all the files in the directory
    const files = fs.readdirSync('/images/');

    // get file from directory
    const myImage = files[idx(files.length)];
    
    // send image to channel
    message.channel.send({ files: [`/images/${myImage}`] });
}

Assuming images are from https://picsum.photos/, here is an basic example:

if (message.content === '!random') {
    const seed = Math.floor(Math.random() * 1000);
    const h = Math.floor(Math.random() * 400) + 100;
    const w = Math.floor(Math.random() * 400) + 100;
    
    // create embed with random image
    const embed = new MessageEmbed().setImage(`https://picsum.photos/seed/${seed}/${h}/${w}`);
    
    // send embed
    message.channel.send({ embeds: [embed] });

    // delete command
    message.delete();
}
