(Answering the questions Michael didn't)
The scripts and plugins in Xtns create a new image -- they're not
tied to any existing image.  The ones in the Image popup menu do things
on the current image.

I learned a lot from "Grokking the Gimp" -- preview it at

That gets my vote for the #1 question on the FAQ!  It was definitely what
kept me in xv or paintshop pro instead of gimp when I was getting started.

And you may not realize this because the "marching ants" may not be
shown for some reason.

The two causes I hit most often:
         * You are painting outside of the layer (because you have
           the wrong layer selected)
         * You are painting to a layer that somehow got "preserve
           transparency set" (which leads to a new FAQ: Why does that
           bit sometimes get set without my setting it?)

I used to hit this problem even back before I knew about layers, when
nothing was selected, and I still don't know what was causing it ...

Ouch.  (That doesn't necessarily solve it, though, since when you reload
you may still end up on the wrong layer or whatever.)
