Pokémon Emerald Tips

Getting Pictures in Lilycove Museum
To get pictures in the museum, you have to talk to the guy in front of the stairs in the museum. Then you have to beat the Master Rank contest and the artist will come out and show you the picture he drew of your pokemon for winning. Tell him yes to put it in the museum and he'll take it there. You have to beat each contest. Which is five contests. When you go back to the museum, there will be more people up stairs and all the frames will be filled. Talk to the guy who told you to get pictures and he'll give you a Glass Ornament for your secret base.
