I use source code from <a rel=nofollow target=_blank href="http://www.ijg.org.">http://www.ijg.org.</a>
It lets make rotate and mirror transformation with jpeg images (it has some restriction for example the size must be divisible by 8 or 16, but it is always true for digicams' photos)

This code is absolutely free, it is used for example in acdsee and internet explorer.

I recommend to include it in your library
