Ich würde auf die schnelle die Array Sotierung von aImagesToDisplay umdrehen.

Hallo,

probier einfach die Liste der Dateien zu sortieren. Vor der Schleife:

Code: Alles auswählen

foreach ($aImagesToDisplay as $sImageToDisplay)
folgenden Code einfügen:

Code: Alles auswählen

foreach ($aImagesToDisplay as $sImageToDisplay) {
    // datum letzte änderung
    $mtime = filemtime($sImageToDisplay);
    // temporäre liste
    $aSort[$mtime] = $sImageToDisplay;
}
// liste der bilder zurücksetzen
unset($aImagesToDisplay);
// sortieren der temporären liste (absteigend)
ksort($aSort, SORT_NUMERIC);
reset($aSort);
// liste der bilder neu setzen, array_reverse kehrt die absteigende sortierung um
$aImagesToDisplay = array_reverse($aSort, true);
Sollte eigentlich so funktionieren, habe es aber nicht getestet...

Gruß
