You would be using custom markup

http://www.pmwiki.org/wiki/PmWiki/CustomMarkup

Markup('latestimage', 'end_',
   '/\\(:latestimage:\\)/e',
   "latestimage()");

function latestimage()
{
	determine the latest image and process
	....

	....

	....

	return (html code of the thumb linkeded to the image)

}
