How to apply the same adjustments to multiple images?

Thanks for all of the responses.  It looks like I'm not the only one with an interest in doing such things.  My apology for not making it clear that I am running GIMP on Windows and I'm most grateful that GIMP still works on Windows 7.

While I do have GMIC installed and even up to date, I'm afraid I haven't used it for much of anything.  Based on my review of everything offered in response to this post it sounds like GMIC is the answer to my question.  For me, I'm going to need to spend a good bit of time learning more about GMIC in order to do that.

Thanks again!
