Why isn't $picture set after the loop terminates?
Because at loop exit, $picture is restored to whatever value it had before loop entry (in this case undef); or more precisely: within the loop, $picture is aliased to each value in turn; outsise the loop it is not aliased and so the name $picture once again refers to the original value.
