Question

I am trying to upload some images and display them inside an empty DIV and after uploading if I mouse hover on an image I should get a delete icon so that users should be able to delete it with an animation and move the next image to the deleted image position.

How do I achieve that?

This is how I am uploading and appending to the div container:

<script type="text/javascript">
 $(function () {
     document.getElementById('Nextbutton').style.visibility = "hidden"; // show 
     $("#uploader").plupload({
         // General settings
         runtimes: 'gears,flash,silverlight,browserplus,html5',
         url: 'Test.aspx',
         max_file_size: '10mb',
         max_file_count: 20,
         chunk_size: '1mb',
         unique_names: true,

         filters: [
            { title: "Image files", extensions: "jpg,gif,png" },
            { title: "Zip files", extensions: "zip" }
        ],


         flash_swf_url: 'js/plupload.flash.swf',


         silverlight_xap_url: 'js/plupload.silverlight.xap'
     });



     $('form').submit(function (e) {
         var uploader = $('#uploader').plupload('getUploader');

         if (uploader.files.length > 0) {

             uploader.bind('StateChanged', function () {
                 if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
                     $('form')[0].submit();
                 }
             });

             uploader.start();

         }
         else
         //alert('You must at least upload one file.');

             return false;
     });
     var uploader = $('#uploader').plupload('getUploader');

     uploader.bind('FilesAdded', function (up, files) {
         //              jQuery('#container a').html('');
         $('#container > *').remove();
         var i = 0;
         while (i++ < up.files.length) {
             var ii = i;
             while (ii < up.files.length) {
                 if (up.files[i - 1].name == up.files[ii].name) {
                     $.msgBox({
                         title: "Ooops",
                         content: "There is already an image with the same filename and cannot be added.",
                         type: "error",
                         showButtons: true,
                         opacity: 0.9,
                         autoClose: false
                     });
                     uploader.removeFile(up.files[ii]);
                 } else {
                     ii++;
                 }
             }
         }
         if (i > 20) {
             $.msgBox({
                 title: "Info",
                 content: "Uuh! Please don't put me any more files.<br>Maximum Upload limit is only 20 Images.<br>Rest of the Images will be removed.",
                 type: "info",
                 showButtons: true,
                 opacity: 0.9,
                 autoClose: false
             });
             $('#uploader_browse').hide();
         }
     });
     uploader.bind('FilesRemoved', function (up, files) {
         if (up.files.length < 20) {
             $('#uploader_browse').fadeIn("slow");
         }
     });


     uploader.bind('FileUploaded', function (up, file, res) {
         $('#container').append("<div class='container a'><a href='uploads/" + document.getElementById("currentDirectory").value + "/" + file.name + "'  rel='prettyPhoto' target='blank'><img src='uploads/" + document.getElementById("currentDirectory").value + "/" + file.name + "' width='64' height='64'/></a></div>");



         var $imageContainers = $('#container a');

         $imageContainers.each(function (index) {
             $(this).delay(index * 50).fadeTo(400, 0.5);
         });

         $imageContainers.mouseover(function () {
             $(this).css('opacity', 1);
             $(this).find('span.del').show();
         });
         $imageContainers.mouseout(function () {
             $(this).css('opacity', 0.5);
             $(this).find('span.del').hide();
         });



         if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
             document.getElementById('Nextbutton').style.visibility = "visible"; // show 
             showStickySuccessToast();
         }
         uploader.removeFile(file);
     });

 });


     function randomString(length) {
         var chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz'.split('');

         if (!length) {
             length = Math.floor(Math.random() * chars.length);
         }

         var str = '';
         for (var i = 0; i < length; i++) {
             str += chars[Math.floor(Math.random() * chars.length)];
         }
         return str;
     }

    </script>

Here is my div where I am showing the Images:

<div id="container">
</div>
