}

Answer 1

Try this function

function getRandomImage(imgAr, path) {
    path = path || 'images/'; // default path here
    var num = Math.floor( Math.random() * imgAr.length );
    var img = imgAr[ num ];
    var imgStr = '<img src="' + path + img + '" alt = "">';
    document.write(imgStr); document.close();
}

Call the function

getRandomImage(ARRAY-VARIABLE, '/images/')
