In PSP there's a very hand perspective tool that allows one to
identify four corners of an object - a rectangle originally, but a
distorted trapezoid in the image. Activating the tool makes the
object a rectangle which I can then crop to get a clean image.

Is there a way of doing the same thing relatively easily in Gimp?

You can use the Perspective tool from the toolbar or press Shift-P. Pick
the Backward (corrective) option and click on the image. This will bring
up a grid you can move to match the perspective of the painting
(anything outside the grid will be trimmed). When you click Transform in
the Transform dialog, the photo will be fixed so it is square.

That's perfect - exactly what I hoped for. Many thanks.
FYI - in Gimp 2.2 what I saw was a box whose 4 corners I moved, rather
than a grid.

If you are at all adventurous... move to GIMP 2.3. It
sometimes does have a rough edge or two on newly added
features, but there are _many_ enhancements to older
features (virtually all of which seem to work
perfectly), and most of the new ones have long since
been polished well enough to be fully functional.
