Placing the texture in the right way

Dear reader,

I have made an animation of the calendar I have made. On the front of the pages I placed the artwork of each month.
When I see the render (image 01) the texture is not in the right way when the page is faling down. When the page is stoped moving we see the right placement of the texture (image 02).
Can you tell me what I do wrong and how I get the image rendered in the right way on the moving page? The picture has to bend as well with the page…

Thanks in advance for your answer.

Kind Regards,
