Access Abrir dialogo de búsqueda de fichero en modo vistas en miniatura.

Hola. Utilizo el siguiente código (disponible en varios foros) para abrir un dialogo y buscar un fichero (para obtener su path y asignarlo a una foto). El cuadro de dialogo se abre en vistas en miniaturas sólo si busco en el directorio Mis Imágenes, pero en los demás directorios se abre en modo lista. Si alguien conoce este código y sabe decirme como modificarlo (si se puede) para abrir el dialogo en vistas en miniaturas por defecto le estaría muy agradecido. Un saludo.
???El código:
