Getting image average from several images

[Satoshi_M]

Hi,

Previously a person asked the following question,
average several identical stacks

but nobody answered the question.

Again I would like to ask the same question.

Does anybody know how to get an average image from several images?
I know there are "Image Calculator" and "Calculator Plus", but they can not treat several images.

I am very happy for your help.
