I am not aware of any existing IDL procedure to do that.
I guess your best bet to get started quickly is to use tools from the
existing libtiff library by Sam Leffler that contains a tool called tiffsplit
which will split multi-directory(page) files into a list of single ones.
You could spawn that from within IDL and provide options to load specific
images into IDL (assuming you split e.g. into a temporary disk area).
The latest version of libtiff can be obtained via anonymous ftp at
ftp://ftp.sgi.com/graphics/tiff .
There are rumors that IDL 5.0 will implement an IDL interface to libtiff
though I am not sure at what level (e.g. if it will allow multidirectory
reads) and more importantly what a realistic release date for IDL 5.0 is.

Christian
