Photoshop to InDesign - want transparent background

I have a tiff image with a transparent background. It's an image of a bag of cookies, transparent background. I save it as a tiff, without flattening it. When I place it into InDesign, the background is no longer transparent and I would like it to be. How do I place the image into InDesign without having the background changed to white?

Thanks

Try saving it as a .psd file, it should place ok with transparency intact.
