I think if PNG is supported by the running Emacs, it is always
preferable.  (And we can come up with the list image formats ordered
by their preference, and use that to find the first available one.)

I do agree that in many/most cases having Emacs deduce the best format
automatically is a very useful feature to have.  I also agree that it
is useful to be able to see the list of available formats and choose
from them.  I just think that these two extremities is all we need,
provided that we can come up with a good algorithm for deciding the
"most appropriate format" in each case.
