This is:

Letter from a higher organization on the report:
Photographs should not be used to 800 KB each.
electronic format JPEG (not to be translated into WORD or other versions).
With respect, xxx

What type of editor can I use to translate a photo into a word format?

Ward of course. "Insert - picture - from the file" or as there in new versions. I am currently writing the book - half of the photos have been brought in this format.
