6.14.3.2 Using exported graphics in their original format

If the original graphics embedded in your document are photographs in JPEG format, converting to BMP degrades the quality of the image. You might consider leaving the exported graphics in their original formats.

Automatically exported graphics will be referenced in RTF provided you load the graphics in Word while the graphics files are still in the project directory. However, the scaling used in FrameMaker is not preserved, so you might have to resize each image in Word. The advantage is better image quality; the downside is the manual work.
