How to implement the jQuery Filer Plugin?

I'm trying to implement a component for uploading images with thumbnails, and I've spent a lot of time looking for one that fits my need. After a day of searching I found the jQuery Filer.

Anyway, I'm having difficulties with the implementation, mainly because I can not use PHP in my solution.

Is it possible to do this with an ASP.NET generic (.ashx) controller?

My HTML:

<form action="GenericHandler" method="post" enctype="multipart/form-data">
    <input type="file" name="files[]" id="input_file" multiple="multiple">
    <input type="submit">
</form>

My JavaScript:

$('#input_file').filer({
    limit: 10,
    maxSize: 10,
    extensions: null,
    changeInput: true,
    showThumbs: true,
    appendTo: null,
    theme: "default",
    templates: {
        box: '<ul class="jFiler-item-list"></ul>',
        item: '<li class="jFiler-item">\
                    <div class="jFiler-item-container">\
                        <div class="jFiler-item-inner">\
                            <div class="jFiler-item-thumb">\
                                <div class="jFiler-item-status"></div>\
                                <div class="jFiler-item-info">\
                                    <span class="jFiler-item-title"><b title="{{fi-name}}">{{fi-name | limitTo: 25}}</b></span>\
                                </div>\
                                {{fi-image}}\
                            </div>\
                            <div class="jFiler-item-assets jFiler-row">\
                                <ul class="list-inline pull-left">\
                                    <li>{{fi-progressBar}}</li>\
                                </ul>\
                                <ul class="list-inline pull-right">\
                                    <li><a class="icon-jfi-trash jFiler-item-trash-action"></a></li>\
                                </ul>\
                            </div>\
                        </div>\
                    </div>\
                </li>',
