This is the core of my ZPT thumbnail viewer.

I haven't finished it or the 'view' object yet, but I use this bit of
code to display my thumbnail views
<table tal:define=3D"photos container/PhotoList" align=3D"center"
cellpadding=3D"0" cellspacing=3D"5">
	<tr tal:repeat=3D"cur python:range(0,len(photos),4)">
		<td tal:repeat=3D"item
python:modules['ZTUtils'].Batch(photos,size=3D4,start=3Dcur)"
align=3D"center">
			<a href=3D"" tal:define=3D"url python:item.getId() + '/view'"
	        		   tal:attributes=3D"href url">
				<p tal:replace=3D"structure python:item.tag(display=3D'thumbnail',
border=3D0, cookie=3D0)"></p>
				<br/>
				<p tal:replace=3D"structure item/title_or_id">title_or_id</p>
			</a>
		</td>
	</tr>
</table>

The 'PhotoList' object is a pythonscript as follows:

return container.objectValues('Photo')

This can probably be replaces with a python: thingie ... just haven't
done it yet.

Hope this helps.
