Hello i'm actually trying to make a bot which tweet a random pic everyday (Kinda like @Raccoonhourly)

But i just dont understand how to pick a random image and make the bot tweet it

here's what i got so far

 const rwClient = require("./twitterClient.js")

const tweet = async () => {
    try {
        await rwClient.v1.tweet("ex. tweet")
    } catch (e) {
        console.error(e)
    }
}

tweet()
