Script "slice using guides" and "png export"

Instead of Flatten you could try gimp-layer-new-from-visible and apply "Slice Using Guides" to that new layer.

Then there is a script that will export all those new images sg-save-all.scm you might pick out parts of that.

By hand it goes:

Make layers visible / not visible
With guides in place Image -> slice using guides.
If required close original image
Use File -> Save ALL As to export in required format.

I am no script writer either, so it is up-to-you.

The old Saul Goode script sg-save-all.scm attached. Unzip put in your Gimp user scripts folder.
