I think that the <dtml-with sequence-item> should be before
everything in the dtml-if. If I'm not wrong, when you make
<dtml-call "manage_delObjects(id)">, you're refering to the
parent object (a dtml method) and not to the object in question.

I think this should do the job:

<dtml-in "objectItems(['Folder', 'ZipFolder', 'Image' ])"
 skip_unauthorized>
  <dtml-with sequence-item>
   <dtml-if "meta_type=='Image'">
     DEL: <dtml-var absolute_url><br>
     <dtml-call "manage_delObjects(id)">
   <dtml-else>
     <dtml-var delimage>
   </dtml-if>
  </dtml-with>
</dtml-in>

Anyway, I think that recursive DTML Methods aren't a good
idea. As Andy said, it's better to use a python script, so that you
won't get confused about Namespaces and it will look cleaner.
