That is the problem; as you noticed correctly, you have to add a
reference to the PhotoImage so it does not get garbage collected. But
you need to add the reference to the PhotoImage object, in this case
photo1, not the PIL Image. Alternatively you can define the PhotoImage
globally, i.e. outside your pic() function.

I hope this helps
