The current version (2.02):
It has 29 different "effects" in all. Ones you
would recognize: invert, flip vertical/horizontal, overlay one
picture on another, adjust colors/brightness, and the rest are
pretty much just things I made up.
Most effects have settings, so you can put your "feel"
It has at least 10 effects that I am almost certain no other
programs can do.
It can read most file types (GIF, JPEG, TIFF, PNG, PICT,
Photoshop formats, BMP, Targa, ICO, CUR, Sunraster, XBM, XPM, and
It can write to those same file types (so, if you have bmps and
want to convert them to the much more space efficient format "jpg",
it can do that)
