Stripfile succeeds mainly by removing embedded comments/text.

"jpegtran also recognizes these switches that control
what to do with "extra" markers, such as comment blocks:
-copy none
Copy no extra markers from source file. This setting
suppresses all comments and other excess baggage present
in the source file.
-optimize
Perform optimization of entropy encoding parameters.
-trim Drop non-transformable edge blocks."

giftrans converts any GIF file into a GIF89a. Allows for
setting the transparent or background color, changing colors,
adding or removing comments. Also code to analyze GIF contents.
SH: These all work on Linux but only MapIvi has a nice interface.
embedded JPEG comments (single and multiple comments are supported):
* display
* add, edit, copy, join or remove
Thanks, David and Stephen. Meanwhile, a gentleman has suggested me
pngcrush, which I have tried with significant size reduction of png
images, with no loss of quality. Please, have a look at:
http://pmt.sourceforge.net/pngcrush/
It is command line oriented and also works on MS Windows.
