By the way, note that LyX (LaTeX) will actually find and read files if
the directory (picts/) with the respective files is there. It just
cannot write into this directory (for security reasons, LaTeX disallows
writing beyond the current working directory, which is the tmp dir
here).

A way which works is this: Create a symlink in the tmp directory with
the same name as the prefix and linking to the respective subdirectory
of the working directory. On Linux, this would be:

\usepackage{shellesc}
\ShellEscape{ln -s <workingdir>/picts picts}

with <workingdir> replaced by where ever your document resides. Of
course, this presupposed <workingdir>/picts actually exists.

HTH,
