I will have an idea about it, I ordered again some independent photos
with my layouts, with and without automatic correction, hoping that it
will be the same for the book printing. What's strange is that I ask
many of my friend and none of them had a "too dark" problem.

That's what I think the only thing I can do (well, I did not know that
CMYK JPEG even exists!).

About the profile, they explain how to do it on this page. It may be in
french, but the screenshots of Photoshop are in english :-)
They propose to work in RGB, then to export to an image using their
profile.

For the moment, I plan to:
1) export everything to PDF with no compression
2) import from PDF to some image format, maybe PNG (hhmmmmm, this
process looks stupid, but I'm not an expert and Gregory advised me not
to export to image with Scribus)
3) convert to JPEG
4) upload images, receive book

I don't know if I should use the profile conversion at step 1 or 3...
Both make sens to me (but I'm not very skilled).
