Hi Matt, I have never worked with nifti images but I know there are problems handling rotated geometries in case of 2D images. If a 2D image is rotated in the 3D space the information about the 3D rotation is currently lost when the image is loaded. As a solution we are planning to handle 2D images like 3D images consisting of one slice. This will be done during the whole geometry refactoring process (bug 8910) but we are currently in the planning/specification phase of the refactoring since these fixes will bring bigger changes in MITK.
