Patrick,

There is some pattern-matching code in the ThumbList recipe [1] that can be 
used directly in attachlist, I believe. The name and skip patterns:


* name="paris_*.jpg|france*.jpg" - display only some files
* skip="*.gif|*.png" - skip some files


The code is roughly this [2] :

function ThumbFilePattern($x)
{return '/^'.str_replace(array("\\*","\\?","\\|"),array(".*",".","|"),preg_quote($x)).'$/i';}

inside the main function:

  if (@$opt['skip']) $skipmatch=ThumbFilePattern($opt['skip']);
  if (@$opt['name']) $pattern = ThumbFilePattern($opt['name']);

later, opening the directory:

   while (($file=readdir($dirp)) !== false){
	if ($file{0} == '.') continue;
	if (@$skipmatch && preg_match(@$skipmatch, $file)) continue;
	if (@$pattern && !preg_match($pattern, $file)) continue;
...

Greetings,
Petko
