Very nice.

Here is a cropped and rescaled picture of my friend Merckle.

I have a few questions though. I first saved the original photo as a
GIMP *.xcf file. Then I did the cropping and rescaling. That resulted
in the above image. I also tried the "resize" setting, which is part
of the crop tool (scalpel), and found that I could not save the image
to *.jpg. It said:

 "Your image should be exported before it can be saved for the
following reasons:
               JPEG can't handle transparency"

What is the purpose of resizing or are you going to cover that later?

 Also I saved the same image as a *.png but the *.png is much larger
than the *.jpg (44k vs 409k) despite the fact that the quality appears
to be about the same. Is the *.jpg format that much better than *.png
? The *.png is here: http://www.silbsd.org/beastie/merckle2A.png
Both were saved from the same *.xcf file.

                                                  Kind regards
