Hi Atulmanohar.
Can you help us out a bit here? Can you tell us whether the
images are not there at all or whether there is a box where the
image should be with an "X" inside? Also can we safely assume you
are using RH HTML?
Whatever the answer, I would think that importing a 600 page
document compiled mainly of images would cause your PC (not RH)
some problems and that the images are inside your project, just not
rendering correctly in the display.
Things to consider is whether you create one topic with the
entire document or split it up. You may also try importing sections
of the document at a time.
Then there is the question as to why you are writting the
document in Word rather than in RH?
