We may need more information about the document data: "The correct
thumbnail filename should be easy as the primary image filename is a
subset of the page URL"? Are you linking to an HTML page, an image,
or some other file download?
The first step is to flag the documents while completing any
additional information such as a summary. Title and filename can be
calculated from existing data.
The automation collects all flagged pages to a list. Cache if process
is slow and frequent. Choose using a random number. (See Andreas
Hartmann's post in this thread.) Cache the number or the results if
stability is desired. Add the resulting snippet to the homepage.

I am happy you like my documentation. More should appear. Migrating
my websites to Lenya 1.3 has higher priority than posting additional
documentation, but most of the Lenya section was collecting and
organizing my posts to the mailing lists so new material depends on
the level of activity on the MLs.
XSL is Turing-complete according to the academics. So is COBOL.
Turing-completeness is about possibilities. Real world programming is
about time to usability and ease of maintenance. The W3C forgot XPath
needs a random() function. XPath 2.0 has been a draft for two years.
Does anybody know how to make suggestions?
