why \graphicspath not work in Windows/lyx?

[Qing-Chang Zhong]

Dear All,

Thanks to Jean-Pierre, \graphicspath would be the best
solution for searching graphics when combining several lyx
files into one file. However, \graphicspath does not work
well in Windows/Lyx/MikTex. It works well with exported tex
files. My lyx is 1.1.6.fix1.

I tried:

\graphicspath{/cygdrive/e/work}
\graphicspath{//e/work}
\graphicspath{e:/work}

but none of them works.

Anyone can  help?

Thanks a lot,
Qingchang
