Andy was very recently heard to utter:
when i insert a clipart file in a blank page, i cannot see it (the
only time i can see it is when a click on print preview ) this will
not work with any other picture.

Check View Pictures. If that fails...

This is almost certainly a problem with your video driver.

By going to Display Properties Settings Advanced Troubleshoot, and
dragging the Hardware Acceleration slider down three notches, you will be
able to disable Publisher from making the calls on the video driver that
cause this problem.

If this does fix your problem, it means that the problem does indeed lie
with the video driver. You can leave your computer running at this lower
hardware acceleration, but it may cause problems with other programs. It is
a better solution to try and find a driver update for your graphics card.
Normally, the latest drivers from the video card manufacturer will do the
trick, but ATI (and recently Intel and Dell) tend to be slower in perfecting
their
drivers, so some newer ATI and Intel cards to not yet have drivers available
that do not exhibit this behaviour. The solution here is to nag
ATI/Intel/Dell for better drivers.
