The middle block of pictures, which were the original ones in the game, probably have the most use in terms of collection items for slightly easier to obtain collections that give tools, artefacts etc. Since they were the first collections in the game they will have least amount of combining elements needed to combine and those combining elements will be slightly easier to obtain. So the 4x3 block Joy Cafe-Amusement Park; Mayan Temple-Throne Room; Misty Shed-Crashed Plane will give you the collection items and combining elements to a larger variety of collections with a larger variety of rewards (tools, talismans etc) that would be considered easier to get in the game.

Tree of Dates is useful since it is the only picture that gives the Pin-Candle combining elements, but you won't need those unless you are trying to get collections from Tree of Dates or some of the pictures that open up at much higher levels (e.g. Tavern). Tree of Dates also gives you the items to make the Valentines Amulet artefact, but you will be playing it a long time to unlock all the items you need, and that will require collecting a lot of cupid arrows. Since the cupid arrows are given out by Venice and Throne Room, then having them open first is helpful so that you can build up a stash of cupid arrows before ever opening Tree of Dates.
