No. (Also, it depends on the options in force: saved images can be ASCII
or binary or compressed or not, and it is impossible to predict how
well compression will work: it can be very effective.)
And please note what the help page says:
Internal functions in the base package, which are only
user-visible because of the special nature of the base namespace.
'sys.save.image' is a system function that is called by 'q()' and
its GUI analogs; 'sys.load.image' is called by the startup code.
These functions should not be called directly and are subject to
change.
'sys.save.image' closes all connections first, to ensure that it
is able to open a connection to save the image. This is
appropriate when called from 'q()' and allies, but reinforces the
warning that it should not be called directly.
so please don't use it.
