Communication between two windows

Question

Hi,
I have a form to store student's personal information. In the middle of the form I have a link named "upload image". When click this link, a new window will pop out for user to upload up to 6 files. I use JSPSmartUpload to upload image, which works fine. When close the pop up window after done uploading, the old window which contains the form need to automatically contain the links to display images uploaded so far. It's like the "attach file" when using yahoo email to attach files. When you done with the attachment, the email will show all filenames you attached so far.
I was thinking that when close the uploading window, the window object will call a reload action target to the parent window. During the reloading, the old parent window will go to database to check the image files and create related links. But the problem is that if reloading the parent window, I think I am going to loose all informations in that form the user entered so far. So, he had to reenter all information.
Can anyone give me some hints about how to accomoplish this task? Thanks in advance.

Can you give me more details? Or give me some website to check. For example, the form is as below:
<form method=get>
<table>
<tr><td><input type="text" name="name" size="20"></td></tr>
<tr>
<td><a href="uploadForm
onClick="popUp('<%=request.getContextPath()%>/fileUpload.jsp', 'uploadWin', '600', '450', 'yes'); return false;"><strong>upload Forms</strong></a></td></tr>
<tr><td><input type="submit" value="continue" name="next.x"></td></tr>
</form>
how to use javascript to get input "name"'s value? where to store them? how to pass this value to the new window and pass it back? Sorry for this simple question. I appreciated it.
Thanks!
