You're right.
But it gives an idea about the file dimensions (kB?,MB?,GB?!).
A Photo in general contains patterns that dont't
compress well lossless. I guess a simple CGI-graphic
like the RSOCP would compressed be smaller because of
single color fields and that.
I should have been more clear on this.

But that's not the point here.
I got the impression some answers in this group are sometime a
bit too sophistivated to help new user with a concrete problem
[e.g. Uneven scaling thread].
That may be just me! Therefore I for myself try to give
simple answers although they may be not completely correct
in a mathematical provable way (I couldn't do this anyway).
This is my policy "as beeing just a PoV amateur"
and I don't want to start a flame war on that!

Sebastian
