When i attempt to resize the window the shape of the image is changed. How to solve this one? Means always the image size and position is same when i resizing the window.

You need to adjust your viewing transformation whenever you resize the window.

You don’t say what windowing system interface or viewing transformation you’re using. In GLUT with a perspective view you’d put glutReshapeFunc(reshape) in your init to register the reshape() method as the resize callback, then define reshape as something like:

void reshape(int w, int h)
{
     glMatrixMode(GL_PROJECTION);
     glLoadIdentity();
     gluPerspective(45.0, (double)w/(double)h, 0.1, 100.0);
     glMatrixMode(GL_MODELVIEW);
}
