You write a python script:

all_images=context.yourimagefolder.objectValues('Image')

table_width=5 # if you want 5 in a row

return [all_images[i:i+table_width] for i in
range(0,len(all_images),table_width)]  

 
You use this pyhon script then in your ZPT:

<table>
  <tr tal:repeat="row here/theScript">
    <td tal:repeat="img row"><img src="img" tal:attributes="src
img/absolute_url; width img/width; height img/height; alt img/getId;
title img/title" /></td>
  </tr>
</table>

like this or you skip the script and the table and
use CSS.

Btw, in mailinglists make sure you post in plain text only.
