If you are only modifying the text in a JPEG, then it follows that you
shouldn't decompress and recompress the bitmap. JPEG was designed as a
presentation format, not one which you can do image processing on.

GIF and other non-lossy compression formats by definition are NOT lossy -
the image does not degrade with decompression / compression.

This is not quite true. IE5 supports it, and so does a number of other
paint type applications.
