exporting layout view in arcpy

Hi,

I am trying to export the layout view in arcmap by using the following script:

import arcpy
import os

mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")
df = arcpy.mapping.ListDataFrames(mxd, "Traffic Analysis")[0]
df.time.currentTime = df.time.startTime

while df.time.currentTime <= df.time.endTime:
# An example str(newTime) would be: "2008-12-29 02:19:59"
# The following line splits the string at the space and takes the first
# item in the resulting string.
fileName = str(df.time.currentTime).split(" ")[0] + ".jpg"
arcpy.mapping.ExportToJPEG(mxd, os.path.join(r"C:\Project\Output", fileName), df)
df.time.currentTime = df.time.currentTime + df.time.timeStepInterval
del mxd

This only exports the "data veiw" map but I want the "layout view"

Is python cabable of this....

I can set the mxd.activeView = 'PAGE_LAYOUT'
so when the mxd is opened it always opens to the page layout. I thougth that would allow images to export from that page but it
doesn't seem to be the case.

Is it possible??
