To change the frame within a category using the arrows

[Japon Guy]

I would like to know how to rotate frames within a category.
I have a frame...
"frames" : [
I am using four {"bmp":"○○.png"}, ] to make it work, but do I need to use width and height to set the frame?
It works when installed as a rotation, but the frame image does not change at all even if you change it with the arrow within the category.
Could you please tell me the plugin template?
