3D Cameras & Null

Question

Hi all,
I am using Adobe Production Studio Premium CS3. I have created clouds using particular with a 3d camera (field of depth is turned on) and a null pick wick is linked to the clouds. The camera only moves on it's Z axis (moving forward, so no particular complex movements.) So you can see the camera flying through the clouds in a staright line.
I have then imported a JPEG image looking down at ocean and land. I have then made the JPEG image into 3D and have done nothing else.
The problem is here. When I put the JPEG into 3D it moves with the clouds 3D and null.
Why?
All I want to do with the JPEG image is for the image to move on it's Z axis at a slower speed than the clouds.
But how do I achieve this?
Thank you
josel

Hi
I have placed the footage on Youtube which is here http://www.youtube.com/watch?v=oUctZYNsS-s
Please ignore the first second or two as this is work in progress.
From viewing the footage you can see the camera flies through the clouds and comes out the other end. You will see the JPEG image (the Oceean and smalls bits of clouds.) Now this is the problem you can see the image staying still. I have not placed a null to the JPEG image at all. The only thing I do is press the 3D button to make it into 3D. When I do this the JPEG image moves at the same speeds as the clouds, which is way to fast for the JPEG.(ocean to be moving.)
Hope this helps to understand.
Thank yoy once again
