Thanks for looking up, but I don't think the problem lies here. We
make a relative path later. See
InsetGraphics::prepareFile():
string const orig_file = params().filename.absFilename();
// this is for dryrun and display purposes, do not use latexFilename
string const rel_file =
params().filename.relFilename(buffer().filePath());
LYXERR0(orig_file);
LYXERR0(buffer().filePath());
LYXERR0(rel_file);
and
GuiGraphics::paramsToDialog():
string const name =
igp.filename.outputFilename(fromqstr(bufferFilepath()));
LYXERR0(name);
I put in some debugging macros you can use to output some debug info.
If you can compile LyX you can try and see what they give you and why
the copies don't get a relative filename.
Stephan ? Can you check this ?

We are thinking about this in a slightly different context. When to
use a relative path ? It is obvious for
"C:\Documents\test.lyx"
"C:\Documents\images\text.jpg"
to represent the image path as "images\text.jpg", and for
"C:\Documents\chapters\test.lyx"
"C:\Documents\images\test.jpg"
to represent the image path as "..\images\test.jpg", but what should we do for
"C:\Documents\chapters\first\firstsection\test.lyx"
"C:\UnrelatedPath\test\images\large\color\test.jpg" ?
Should we now have a relative path
"..\..\..\..\UnrelatedPath\test\images\large\color\texst.jpg" ? This
doesn't really make sense.
