    // Sample output:

    // The file contains a quote from William Shakespeare's "Romeo and Juliet" and an image of Shakespeare. The quote is from Act 2, Scene 6:
    // 
    // “These violent delights have violent ends
    // And in their triumph die, like fire and powder,
    // Which as they kiss consume. The sweetest honey
    // Is loathsome in his own deliciousness
    // And in the taste confounds the appetite.
    // Therefore love moderately; long love doth so;
    // Too swift arrives as tardy as too slow.”
