ok, I understand...
You can disable the frameanimation by setting:
However, I dont think this fully creates the effect you are looking for. The frame is a static part of the gallery(unless set to false), while images come and go, and fade in and out by transitions. In other words, you wont be able to set an effect so that the entire frame fades out along with the image.
I do understand your request, so I will keep it in mind for the future ...
