[Zope] Uploading image files via forms ...

[Darran Edmundson]

My original question was how to check if the user
omits the filename in a submitted form:

  <dtml-if newimage>
      <dtml-call "manage_addImage('id', newimage.read(), '')">
  </dtml-if>

One option was to use name="filename:string:ignore_empty" 
but this seems to confuse Zope's content-type recognition
when a file is actually selected.

Kevin Dangoor suggested:

The first does not work.  The second does!  Thanks very
kindly.
