I know if I click the Sized Image I can see the Panasonic full size image "raw". But, would rather see it with some formatting akin to the theme.

If I took archive.php and stripped out gallerytitle div and tag_cloud div and add to the padbox div something to call the image, would it display? The page would be called within the image description, using the URL from the raw image. The newly crated php pages would reside in the /album folder

PSEUDO CODE:
whereby the "show the image" would be proper PHP code that I ain't got a clue about to display the requested image to screen.

You do not need to userp the archive.php script. You can just create a new page with whatever formatting you want--say fullimage.php. Then you make a link to 'http://mydomain/zen///page/fullimage`

thought the basics of archive,php provided the starting point.
much as it's mentioned for extra pages such as about, contact
