> Just curious. What is a pyramid tiff file? 

Its simply an image that has multiple layers of smaller and smaller versions of
the same image (e.g. 256x256, 128x128, 64x64).  That way a web site, for
example, could just select the appropriate sized version of the image and
display it without needed to perform an expensive real-time resizing operation.
