Talk:List of Pictures/@comment-97.81.247.98-20150720040617/@comment-24668482-20150720125035

The order here is the order they were introduced to the game. You can open them in any order you like really, but in terms of artefacts most of them require the first pictures in this list before the later ones. Except the Valentines amulet which will need tree of dates (but quests won't trigger until you open tree of dates). I think if you have the first 12 pictures on this list then you should be okay, and order of the rest not that important. And that goes for tools too, the first 8-12 in this list will get most of the low level collections that award tools for you.
