Ok, it's possible as I said in another thread.
Imagevenue.com does it.
I found a site that has a flash program that says it can be integrated onto any o/s into a PHP script.
Code:
MultiPowUpload system requirements:
Server's side:
Any OS and web server.
Standard script which receives files on server. ASP, ASP.NET, PHP, JSP, ColdFusion and Perl examples are included.

Would someone possibly be able to integrate it into vB to allow batch-selecting of files to upload as attachments?
