"Creating an appropriately sized image" opens a whole new can of worms. See
   http://www.php.net/manual/en/function.gd-info.php#52481
for some code to simply get the GD version, and GD isn't available on
all installations. Consider also that many sites will prefer to use
e.g. Image Magick for resampling images.

This proposal is for something far simpler, where the thumbnail is not
really a thumbnail but the full-size image displayed thumbnail-size by
the browser (like the current %thumb% wikistyle does).  No new images
or pages are created.

The way I see it so far, it's two parts:

1) Special markup like (:thumb Attach:Test/SomePhoto.jpg:) generates a
self-referring thumbnail link with
?action=viewimage&image=<url_of_the_image> .

2) When a page is requested with
?action=viewimage&image=<url_of_the_image> the image is displayed
within a template page (maybe Site.ViewImage).  A default template
might render a page that looks like

    http://www.pmwiki.org/wiki/Test/ImageThumbLink-Img1

Thinking about it... maybe just the image name, rather than a URL,
would be better.

p.s.: I think a PmWiki image gallery with resampling will be an
important and useful addition.  It's just not what I'm proposing here.
