As it happens, I have just been trying to do similar:
Somebody asked me to look at a pdf that wasn't working for everyone who
tried to access it from a web site. It turned out to be just several
scanned pages from a newspaper, which were poor quality and yet made for an
overall huge file. So, if by 'convert to a Word doc', the intention was
really to convert graphical representations to text and thus save huge
amounts of space, then I am sure lots of people would like to do this.
Unfortunately, though large files, the 'text photos' had not been scanned at
the 300dpi minimum my 'readiris' software needs for the conversion. As I
can still clean up the pictures quite a lot visually in 'Photoshop
Elements', I had hoped this might enable the conversion, but, the letters
still appear completely pixellated in the 'learn' window. I wondered if
perhaps I could print off my 'cleaned' images and then rescan them, but by
this time it was all getting rather time consuming, so I have not looked any
further at this.
A further reason to import jpgs into Word - if the question wasn't really
about converting to text - is to make them one of the objects in a picture,
to which you can add annotations and other symbols before recombining them
into one image. I often import aerial photos from one source, and the
corresponding scale map from another, before making annotations and comments
and combining all into one picture. This is very useful in preparing
reports on wildlife sites for example (and such an image can then form a
useful basis for a Google Earth placemark...).
Word is very handy for juggling stuff around like this if you don't have
loads of other expensive dedicated software.
