[Zope] length of an object

[Satheesh Babu]

Here's how I'm checking for the dimensions of an uploaded image. You could
similarly do the size as well.

<dtml-if "(_.int(_.getitem(_['tmpimageid'],1).getProperty('height')) > 150)
or (_.int(_.getitem(_['tmpimageid'],1).getProperty('width')) > 200)">
    <B>Error:</B>your image is bigger than 200x150!
  </dtml-if>
