it means exactly what it says: when created, the PhotoImage class
registers a photoimage object with Tk, but when you try to use it in
FooModule, it's no longer there.

are you perhaps using multiple root windows?

(each root has its own interpreter context, and images registered
in one context aren't visible in other contexts.  use Toplevel in-
stead).

Cheers /F
