Here it is running the pertinent lines in the REPL.
It seems like the download does not work I think.
julia> fname = joinpath(tempdir(), "standard_test_images.zip")
"C:\\Users\\Jacques\\AppData\\Local\\Temp\\standard_test_images.zip"
julia>
download("http://www.ece.utk.edu/~gonzalez/ipweb2e/downloads/standard
_test_images/standard_test_images.zip", fname)
ERROR: spawn: no such file or directory (ENOENT)
