You could also try to first turn off the Preference "Save FrameImage
with imported graphics", restart Frame, open the document, re-import
the JPG file, and resave the document. When you save documents with
imported graphics, you can select to save one or two "images" of each
graphic: the original one (JPG), and one (usually much larger)
Frame-specific cross-platform one (FrameImage).
Usually, you don't need to save the FrameImage, so turn it off. You
shouldn't get the message when you save any longer.

Weird enough, when I try this on Windows, there's no change in the file
size... The file saved on UNIX is considerably smaller, though.
Maybe I did something wrong, but it should be smaller without the
FrameImages. Try it on your FM installation.
