tkbd,
Usually when one gets a "No image rendered" message it is because no image is rendered. This can happen with Photon Mapping and/or Pathtracing, if not enough photons are present. You will usually see a message similar to the following in the Log window when that happens. The solution is to add more lights to the scene...
INFO: PhotonMap: Building diffuse photon map...
INFO: [ ] (0%)ERROR: PhotonMap: lightPDF sample error! 0/0... stopping now.
It is strange that you are getting a successful render when this happens. Maybe it is different with OSX.
I do not know if Wings3D can be changed to add the actual rendered name instead of <<rendered>> to the Outliner. This is how it works for Kerkythea and Pov-Ray as well. I may have requested this in the past, if I remember right. I think the response was that the Wings file is not intended to be a container for rendered images. I will usually rename <,rendered>. to a new name in the Outliner if I get a good render and then make it internal for safe keeping.
We will have to see what dgud and/or micheus have to say...
