Yes. Please note that me picking out a specific point does not mean your
other requests won't be answered by somebody ;)

How would you get the compression level? Before you save it there is no
such thing as a "compression level". For png, it would be between 0 and 9
(on gimp), for jpeg it's 0..1 (in gimp) etc... for other formats there
is no compression level at all.

that's not what happens with jpeg. you can't, in general find out the save
quality as this is a number not really defined in the jpeg "standard".

please also note that it's disagreeable wether saving the image with the
same compression level does have any sensible semantics at all.

a pity that this indeed cannot be changed (but also note that a level of 1
does not mean the image won't be "damaged").

Such a thing doesn't exist. Do you mean compression level 1? That's not
the same as no compression.

I think the jpeg save plug-in does indeed do previews, do you mean
something else?
