Thanks Steve, I just found a short thread in the archives but it didn't seem to reach a definite conclusion. Seems that TIFF makes no provision for storing partial bytes of data in less than full bytes of storage space. The only downside to this is waste of storage space and increased read/write times. Kinda like being in the old FAT days again. ;-)
