Let me know how it goes.

OK, I didn't get that there were external dependencies.

Fair enough, could you point me to some documentation that describes the
public interface of io_new library ? I'll see if I can conform to it.

At the expense of additional external dependencies, yes. ImageMagick could
be another candidate, or XnView API, or DevIL, or OpenImageIO - there are
many flavours out there, depending on features required by people - it would
be hard to match everyone needs. I'm pretty glad with FreeImage right now
for my needs, so I'm not ready to invest time elsewhere.
