Actually, once you beat the game once, you can start the game over with the same file. You keep all of the figurines you had beforehand, you start out with the Deluxe Picto Box, you can understand the Hylian that Jabun and Valoo speak, and you wear your pajamas the whole time. Lots of people do that because it's hard to get them all your first time. Sometimes, it's even impossible to get it all on the first try because of a couple pics that can only be taken earlier in the game, before you acquire the Deluxe Picto Box (like if you defeat the tornado frog too early).
