Thank you for responding so quickly!

You are going to love this. Currently, I need to be able to handle TIFF images up to 4 GB and in the near future I am sure I will need to work with larger images. My company prints 4 color billboards up to 63 feet by 32 feet, the project I am working is for printing 360 dpi up to that size. I have printed images derived from 2 GB to 4 GB TIFF images before. These images were created in Photoshop 7.0 (with the 2 GB file limit) and then strung together with some propriety software which used one data line per strip. We were hoping that Photoshop 8.0/CS on the G5 would eliminate a step. In the near future I am going to need TIFF files up to 8 GB and maybe larger. So I am going to have to work on a 64 bit version of libtiff.

But you won't get them -- TIFF has a 4 Gig hard limit (because of the 32 bit length/offset values).

Anything over 4 Gig will need a different file format.
