Dynamically change orientation for particaular page in word?

Question

Hi,

  i have to get different images from database and insert into a word document,but each image has to be placed inside the word document depending on the orientation of the word s page.

i.e
for every process i have to insert images into the same page of the word document,so i need to dynamically change the orientation of that particular page depending on the image being inserted.

Please let me know how can i dynamically change orientation of one particaular page in word using C#.

Regards,
Dilip.
