Notes for multipage images (TIFF and GIF):

By default, the class loads multipage images (GIF and TIFF) in read & write mode.

To open multipage images in read-only mode call the TiffOpenMultiPageForWrite() method specifying False for tiff images or the GifOpenMultiFrameForWrite() method for gif images.

This method requires the Image Documents component to run.
