Hi Stuart,
when you compare these images with IM (e.g. compare IMGP3685.jpg
test3685.jpg  x: ) you'll see that a lot of pixels are affected by the
watermarking (unchanged pixels are shown white, changeds red). Maybe
these overall changes allow a better compression then?
I would have expected that only the image region with the watermark
would be affected. But this should know a digikam insider/programmer.

I tried same watermarking in batch queue here (dk 2.4.0, KDE 4.13.2)
with the same your result.
