Answer 1

val calendar = Calendar.getInstance()

when (calendar[Calendar.MONTH]) {
  1 -> //set first month picture
  2 -> //same
  ...
}

Get a calendar instance using getInstance(), this will return a calendar object initialized with current device time/date. You should get an instance in onCreate() of your activity/fragment and from there you check the current month and apply the image accordingly.
