I would like to know if it is possible and how to customize the layout of my
document.

I have 20 pages of written work. On the 15th page I have inserted a diagram
that is quite large. I would like to change the layout of that one page to
horizontal and keep the rest of the document vertical. The reason for this is
that it is part of text and I would like the automatic page-numbers and
image-text to stay in the right order - hence I can't make this diagram into
an appendix.

Your help will be much appreciated!

Thanks
