Hy,
Try test and use this example.
The user can add text-fields, but you can replace it with type="file"

<script type="text/javascript">
<!--
// - www.coursesweb.net/javascript/
// creates an input element and adds it before the Submit button
function add_input() {
    var new_input = document.createElement("input");
    new_input.setAttribute("type", "text");
    new_input.setAttribute("name", "nume[]");
    new_input.style.display = 'block';             // Seteaza display:block; pt. a afisa casutele unele sub altele

    // sets the objects for reference (reper) and parent
    var reper = document.getElementById('submit');
    var parinte = reper.parentNode;

    // Adds the new element
    parinte.insertBefore(new_input, reper);
}
//-->
</script>

<form action="">
    <input type="text" name="nume[]" />
    <input type="submit" value="Submit" id="submit" /><br /><br />
    <input type="button" value="Add field" onclick="add_input()" />
</form>
