I don't have XSI in front of me, but here it goes.
You can extract a texture projection with the texture lookup node. I
don't remember if that particular shader has controls to offset the
coordinates, but if not, plug it in a texture_edit shader, which is
meant specifically for this.
Finally, instead of using an Image shader, use an image lookup shader.
Plug the image clip and the texture_edit shaders in the inputs.
Cheers
