I guess the simplest workaround is to change the working directory
before you call Sweave(), i.e.
  setwd("C:/temp/")
  Sweave(testfile, output = "myfile.tex", stylepath = FALSE)

This is about the 
  \includegraphics{}
statement within the TeX file. Of course you can set each one of these
explicitely giving the full path to the graphics file, but I guess this
is rather cumbersome.

You need to do that in the .Rnw file, e.g.

<<fig = TRUE, include = FALSE>>=
plot(1:10)
