Hi Phummipat, The osg::Image::scaleImage() function in OSG-2.8.x and before relies upon GLU library's gluScaleImage which requires a valid graphics context to run and will generate errors or crash when called without a valid graphics context being current.
In the latest OSG dev releases and svn/trunk we have moved to use an internal GLU library rather than an external one like before, and this internal GLU is modified to all ScaleImage functionality that doesn't require a graphics context to run, so your type of usage will work just fine. Please try svn/trunk or OSG-2.9.10. Robert.
