3D rotate loaded image

I am trying to use rotationY and rotationX on an externally loaded image. The image loads properly when no 3D rotation is applied, but does not appear afterwards. I have tried various things: loading the image into a bitmap, loading that bitmap into a Sprite/MC. What am I missing?

Just to be sure, regular rotation works fine, e.g

PHP Code:

---

pic.rotation = 2 


---

Use a mature image rotating tool to adjust single or batch image directions so that the source image format can be correctly displayed on the computer screen. Please check out method below:

Public Shared Function ApplyRotate(img As REImage, deg As Integer) As Integer
