I've started to learn to use tkinter but can't seem to rotate images.
Here is a Python 3.4 program to illustrate the problem.

I tried a simplified version of this in the Idle shell. Idle displays
call tips if you pause after typing '('. Unlike .pack and .grid, .place
apparently does not automatically put the widget in its master. At least
this is true when placing in a canvas. You need an 'in_' argument (the
'_' is needed to not be the keyword 'in'). Try
canvas1.pack() #don't use place unless really needed.
...
myButton1.place(in_=canvas1, x=500, y=300)
