Original plugin by tomoaky.
-----
While the picture is displayed, clicking (tapping) on the opaque part
will activate Common Event 1.
(The number indicates the Common Event number that will be activated.)

Example: Clicking on a picture with the file name Actor1_CE4.png
will activate Common Event 4.

Note:
Rotated or enlarged pictures are not supported.

If you change the file name to change the Common Event that will be activated,
you will also need to re-specify the image file in the Event's Contents.

There is no plugin command.

注意:
  回転または拡大しているピクチャには対応していません。

  起動するコモンイベントを変更するためにファイル名を変更した場合、
  イベントコマンドの方でも画像ファイルを指定しなおす必要があります。
