You can load the image into a vtkTexture, create a vtkPlaneSource with
height and width sized according to image dimensions, pass the plane
through vtkTransformPolyDataFilter then a mapper and actor. Apply the
texture to the plane with actor->SetTexture. Use the transform to position
and orient the plane as desired in 3D.

There should be an example or 2 in vtk, try the examples related to
vtkPlaneSource perhaps?
