I hope that you did not take my example literaly. I included an extra
apostrophe (')
in the example that would give a syntax error. Here is a simplier example.

<dtml-var "blah(REQUEST, alt='your text', pdcookie='1')">

Add all the additional tags that you would want. Remember that blah needs to
be photo object, not an attribute with the name of the photo

If I understand your problem correctly, you should be able to do this.
<dtml-with blah> # blah is an attribute of the index_html document
  <dtml-var "tag(REQUEST, pdcookie='1', alt='your text')">
</dtml-with>

Also, you could loop through all the Photos in a container as follows.

<dtml-in "objectValues('Photo')">
  <dtml-var "tag(REQUEST, pdcookie='1', alt='your text')">
</dtml-in>

The pdcookie feature is nothing more than a switch to spit out some html.
