    Img Collection

    Hi,

    In my ASP.NET Webform page, I have a fileuploader and a div. On single selection of image, the selected image is added to the div. All works fine. Now, I would like to add a checkbox or some sort of selection and then save the selected images to the server folder. Please can someone help on how to do it?

    Thanks
