Hi Cork,

generally, MetaMod is all about deciding which other module to display, then telling Joomla to display that module. However, there are various features that can be used to generate the contents of a module without actually pulling in a pre-made module from the module manager.

So, my first recommendation would be to look in the Joomla Extensions directory for a module that can display the most recent image in a folder, and forget MetaMod.

If you can't find anything, then you could use some code like this inside MetaMod:

$path = "/path/to/images/myfolder";
$latest_ctime = 0;
$latest_filename = '';   

$d = dir($path);
while (false !== ($entry = $d->read())) {
  $filepath = "{$path}/{$entry}";
  // could do also other checks than just checking whether the entry is a file
  if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
      $latest_ctime = filectime($filepath);
      $latest_filename = $entry;
    }
  }
}

// now $latest_filename contains the filename of the newest file

if ($latest_filename != "") {
  echo '<img src="/images/myfolder/' . $latest_filename . '" />';
}


Hope that helps,
Stephen

p.s. this is untested but is probably very close to being right!
