Partially correct.  There is an
osg::Image:::readImageFromCurrentTexture(..) that allows one to
convert the current bound texture to an osg::Image.

I didn't suggest attaching an osg::Image to osg::Camera at any point.

What I would suggest is using a osg::Camera  FinalDrawCallback to do
Image::readPixels().  Have a look at the osgscreencapture example.
