Removing JPG artifacts with GIMP

This is remarkably easy. Filters --> Blur --> Selective Gaussian Blur.

Default, when the dialog box comes up, is 5.000 and 2.000. For the artifacts I find, settings of 1.0 and 0.62 seems to remove them with minimal loss of picture detail. Lower than 0.62 you can still see artifacts.
