I wrote it in haskell, just reading file and writting it out using ByteString:
import qualified Data.ByteString.Lazy as BL
main = runFastCGIConcurrent 1000 (handleErrors cgiMain)
cgiMain :: CGI CGIResult
cgiMain = do
setHeader "Content-type" "image/jpeg"
b <- liftIO $ BL.readFile "/usr/lib/cgi-bin/pic.jpg"

I am planning to write complex content management system with storing pictures in dedicated storage, that's why I have to output pictures through the application.

So, I will use something different than fastcgi.
