PNGs are allowed!

[Admins]

What IE version?
Png is much better than gif,
the compression is much better
and you can use 24bit colors -
if you compare a Graal screenshot
that takes 60k (when having
many lights on it) with a JPEG
then you will see the difference
I always must reduce the screenshots
to gif/jpeg before uploading them
as screenshot of the day :-(

I guess gifs are still popular because
there are good editors and
animated pngs (mng) are not supported
by many programs
