Add on drop event to a div javascript

You need to enable dropping on the target element. Add the ondragover attribute to your div like this:

<div id="bin" ondrop="drop(event)" ondragover="allowDrop(event)">
    <img src="icono.png" style="width:100px; margin-left:500px;display:inline;"/><p>
</div>

and an allowDrop function such as this:

function allowDrop(e) {
    e.preventDefault();
}
