Results
*******
I do not see problems as the document is relatively large - 71 pages with lots
of large images resized to small but will take same amount memory as they were
large - I described it already previously. Navigator shows 243 graphic objects
under images. There might be even more as the Navigator cannot count all
graphics due to misspelled names.

I would say that any office suite will be slow with that file due to large
amount of large images resized into small to view but inserted as large.

Suggestions
***********
1) Leave the document into MS OneDrive as is - everyone can access and download
if needed.
2) Use some web-based image gallery to upload images and comment them as
needed. such web galleries will resize images automatically as they needed.
3) Resize images as needed and then insert them into document.

About resizing
**************
E.g. 7,79 x 5,84 cm image is inserted as 21,59 x 25,40 cm (1280x960 and takes
630,9 kB). Resizing does not help - the image will take same amount of memory
as it was in original size. Let's say you have 243 images and one image takes
~500 kB of memory. Then all graphics would take ~121,5 MB of memory.

I resized 1280x960 image to 300x225 with 85% of quality with GIMP 2.8.14 and
got file size from 630,9 -> 22,2 kB. This is ~28,42 times smaller! But as you
are using quite small size of these pictures, there is no point to insert them
as large as they came from camera.

So very roughly calculation would say that you could have ~6 MB instead of ~160
MB for that file. Even if you will have a bit more then anyway it would be much
better than have 160 MB...

So if you still consider it as a bug - please add your considerations so
developers can take further steps.
