2 vraagjes over bestaande gallery

ik heb het script hier gebruikt van ik geloof bas en het werkt prima alleen wil ik er twee dingen op uitbreiden als dat kan.

- ik wil graag maar 12 thumbs per pagina en de rest op een nieuwe pagina, hoe doe ik dit?
- ik wil graag de fotos op volgorde getoond hebben, dit moet in een array dat weet ik maar ik kom er niet uit.

dit is het script.
