Looks helpful.  I'm basically using a slightly hacked version of the
upload function you use Pm, with the ability to change the redirect
page.  I'm assuming I could reset the upname function after the file
has uploaded (form has been submitted, ZAP is called), and before the
upload function you wrote executes.  Is that correct?

I could do the same for retrieving type, and size, say perhaps to use
conditionals to further limit how zap uploads work, right in the form
itself.  Cool.
