Now that I played around with this a little more, I think what I am looking
for is the ability to create a custom shape.  I see that you can display your
picture in common shapes such as a trapezoid or parallelogram.  If possible,
I would like to have a little more flexibility than these common shapes give
me.  I was wondering if there is a way that I can create my own shape either
by moving the vertices of one of the common shapes or by connecting a series
of lines to enclose a particular area.

If anyone could tell me if this is possible, I would really appreciate it.

Thanks again,
Paul
