[Haskell-cafe] Can we come out of a monad?

[C K Kashyap]

Hi,
In the code here -
http://hpaste.org/fastcgi/hpaste.fcgi/view?id=28393#a28393
If I look at the type of modifiedImage, its simply ByteString - but isn't it
actually getting into and back out of the state monad? I am of the
understanding that once you into a monad, you cant get out of it? Is this
breaking the "monad" scheme?
