I tried your OpenNtf database, I just customized your multiple image uploader xpage to fit in my requirement.
I have modified Div as below:
<div class="fieldset rows" id="imagesQueue" ondrop="drop(event)"
var FileList = ev.dataTransfer.files;
for (var i = 0, f; f = FileList[i]; i++)
After this its showing files inside the div having id 'imagesQueue'..
But problem is that when I clicks on the Start All uploads button it only processes files which are not selected by using Drag and drop.
Please let me know if I am making any mistakes in adding files in the Queue.
Thanks and regards,
