Alt attribut about imager.js

[firegoby]

I haven't got time to test this today, or push an actual update, but this should do it...

Add just after Line bbc#139 in Imager.js

if (divs[i].hasAttribute('data-alt')) {
    gif.alt = divs[i].getAttribute('data-alt');
}

Hope it works, let me know, thanks
