# คุณสมบัติ :
# 　แสดงรูปไอเท็มด้านขวาของ Scene_Item
#------------------------------------------------------------------------------
# วิธีใช้ :
# 　นำสคริปต์นี้ไปวางเหนือสคริปต์ Main และใต้ Scene_Debug
#    หารูปที่จะใช้แสดงประกอบไอเท็มไอดีที่ต้องการ กำหนดชื่อได้จากส่วนตั้งค่าข้างล่าง ใส่ในโฟลเดอร์ Pictures
#    **ไม่จำเป็นต้องหามาใส่ทุกรูปก็ได้ ไอเท็มไหนที่ไม่มีรูป จะเป็นช่องว่างๆ เอาไว้
#==============================================================================
