Web Forms :: File Uploading With AsyncFileUpload?

I have a Web application in which I'm trying to use the new AJAX AsyncFileUpload control. I want to use it in the ModalPopupExtender, and I want to embed these two AJAX controls in a user control (photo_upload.ascx) for re-use in different parts of the application. (I understand that this wasn't possible with the older FileUpload control but that it is with this most recent AJAX tool.)

Presently, I merely redirect the user to an upload.aspx page that includes the photo_upload.ascx control (see the sequential screenshots in the attached image); but while this way of doing things "works," it becomes very confusing for the user who has already clicked an upload button or two. In other words, when the "Add Yours" button is clicked, the panel with the "(1) Upload Photo" button unhides; and when the Upload Photo button is then clicked, the user is redirected to the control in the bottom screen. I would gladly bypass the 1, 2, 3 steps in the second screen after the "Add Yours" button is clicked and redirect straightway to the upload control (in the bottom screen, which I will like to be in a ModalPopupExtender), but I also need a way for them to enter a caption that will go with the uploaded photo.

My VB code for the above steps is included below. I would appreciate any fresh ideas on how to accomplish my above objectives.
