Hi Bob
Could it be XEP 4.10? I'll move to 4.13 and check. I can't see the
Java version being responsible. I checked several times with my
too-chain, it is reproducible with XEP 4.10.

Do you see the picture without doing the 'copy' xsl first? I don't.

Sorry, I omitted the directory structure. You are right, the files are
all in one directory and images is a subdirectory. I expected images/...jpg

The XInclude processing seems to be fine, no problems. It is only the
file that is referenced by the nested XInclude that gets the wrong (full
and duplicated) path and I don't see the picture. As I remember the
2005 problem did not generate full paths, it just duplicated the
'images' directory. maybe I am wrong in thinking it the same problem.

No, nothing via a catalog. The only full path I have is for docbook.xsl
I'll post when I've checked with XEP 4.13.
