Joris, I currently keep the offset of the last IFD in memory as long as I have a particular TIFF open and use and update that offset value when I append an image. The main challenge is determining that offset value when I first open the file without having to do hundreds or thousands of seeks. I therefore started writing the offset value, along with a signature and CRC, to the end of the TIFF file, so that as long as I am opening a file which my app created, I will find that offset.
