メインメニューのデフォルトのアクターレイアウトを変更して、/img/pictures/から垂直画像（バスト画像）または縦画像を使用するようにします – GALV_BustMenu.js

Galv's Bust Menu
----------------------------------------------------------------------------
This plugin changes the layout of actors in the main menu. The plugin
includes settings that allow you to change the positioning of the actor
data (such as name, level, hp, image, etc.) including how many actors will
appear on the menu screen. (NOTE: 1 actor is not working)

The plugin displays bust images from /img/pictures/ folder based on the
actor's face. For example:
If an actor uses the 2nd face from the "Actor1" faces file, then the bust
will instead use /img/pictures/Actor1_2.png bust image.

----------------------------------------------------------------------------
Bust Offsets (Scroll down the plugin settings to find this)
----------------------------------------------------------------------------
Bust images are centered in the actor positions, but sometimes the bust
images are not centered themselves. This setting is used to tweak the x,y
position of busts if required.
To add an x,y offset to busts, add data to this setting as below:

bustImageName_1,x,y|bustImageName_2,x,y|bustImageName_3,x,y

Each image and data are separated by a pipe (the "|" symbol). For example:
Actor1_2,-10,0|Actor1_5,20,5
The Actor1_2.png bust will be offset 10 pixels to the left
The Actor1_5.png bust will be offset 20 pixels to the right, 5 pixels down
