Yes, but realize that JPEG files still create a much larger overhead
compared to other bitmap formats, due to the bug I referred to.

Is there a compelling reason for using JPEG for screenshots?
JPEG is a format made for realistic images, like photographs, with
smooth color transitions and without sharp edges. Screenshots are
generally saved more effeciently by using a format such as GIF
(limited to 256 colors), TIFF or PNG. Even if a GIF/TIFF/PNG file
becomes larger than the JPEG file, you could still get smaller FM
files due to the bug with embedding JPEG files. If you make sure
the preference "Save FrameImage..." is turned off, you won't get 
the extra overhead created with embedded JPEG files.
