I believe PostgreSQL accepts slashes as a separator on Win32 (I used
it that way with COPY), but if you want to use backslashes, you have
to escape them:

INSERT INTO IMAGE
VALUES ('chanukya', lo_import('D:\\Vivek\\Personal\\PICS\\IN\\chanukya.jpg'));

Also, I'm not sure if Penchalaiah means that "Server" = "my system
itself", double check on that.

Good point.  I presume that PostgreSQL will look at the path relative to the server, not the client.  I personally keep my files in CVS and just put references to the files in PostgreSQL.  Of course, I had to write the code that automatically checks the files into CVS but it works quite well.
