Question

Ok, i have a javascript function which toggles the innerhtml of a div tag when a user changes the option of a select dropdown box..

It all works fine with text, but

Answer 1

It seems to me like you forgot to escape the quotes surrounding your image paths, and its not reading your string correctly, try this

function toggle(opt) {
    var d = document.getElementById('div_tag');
    if (opt == '5') {
            d.innerHTML = '';
    }
etc...
