Hmm, this would probably be a *lot* easier in PmWiki 2.0.  But here's
a shot at a 1.x implementation:

First, define the gallery: intermap link (in local/localmap.txt) with:

    gallery    http://www.example.com/pmwiki.php/Group/LargeImage?img=$1

Next, add the following to your local/config.php:

   $DoubleBrackets['{$Img}'] = $_REQUEST['img'];

Finally, in the LargeImage page, put the following markup where
you want the passed-in image to be displayed.

   http://www.example.com/path/to/images/{$Img}


Okay, let's see what happens.  In any wiki page you can put
the markup:

    [[gallery:photo.jpg /path/to/thumbnail]]

gallery:photo.jpg becomes a link to 
http://www.example.com/pmwiki.php/Group/LargeImage?img=photo.jpg -- 
i.e., it jumps to the LargeImage page and has the desired image 
passed in the img= parameter.

Inside of LargeImage, the sequence {$Img} is replaced by the
value of the img= parameter, so the markup

   http://www.example.com/path/to/images/{$Img}

becomes

   http://www.example.com/path/to/images/photo.jpg

which is then converted to an inline image in the LargeImage page,
which I think is what you wanted.

How's that?
