Any way to record actions taken on one image and apply them to entire directory?

I am not a frequent or expert GIMP user, in fact I don't do a lot of image editing at all, and most of what I do do is very simple stuff like cropping an image. So please don't assume I have a lot of prior knowledge about GIMP. What I was wanting to know is if there is any way to load an image, record the actions I take to modify that image and the options used when saving it, and then apply that to several hundred other images in a directory.

To be more specific, what I have is several hundred images that have a significant transparent border. All I want to do is automatically crop the images so that all the excess transparency is discarded. If I were doing this on a single image, I would do it this way:

•     Load the image
  
•     Use the fuzzy select in any corner to select the transparent part
  
•     Invert the selection (If there is a better way to select non-transparent parts only, I'm not aware of it).
  
•     Crop to selection
  
•     Export the image as a .png file to a different directory but with the same filename, with none of the options selected in the popup that you get when you export a .png image (basically I uncheck everything, also I make sure maximum compression is selected).
  

That's easy enough on one image, but the thought of having to do it a few hundred times doesn't thrill me in the slightest. Is there any easy way to do this?
