Hello,

I have a problem with the "Save session" command of 3D viewer.
Basically, the .scene file doesn't keep track of the image filename.

Reproducing the bug:
1) Create a stack, save it (temp folder), close it, open it again and import it to 3D viewer:

  close("*");
  newImage("Untitled", "8-bit black", 256, 256, 50);
  setSlice(25);
  makeOval(59, 70, 121, 115);
  setForegroundColor(255, 255, 255);
  run("Fill", "slice");
  temp = getDirectory("temp");
  saveAs("Tiff", temp + File.separator + "stack.tif");
  run("Close");
  open(temp + File.separator + "stack.tif");
  run("3D Viewer");
  call("ij3d.ImageJ3DViewer.add", "stack.tif", "None", "stack.tif", "0", "true", "true", "true", "2", "0");

2) Save the session and load it again (don't know how to do it in a macro, sorry). 

=> "Cannot load image: Untitled".


Here's what the .scene session file looks like (beginning omitted for conciseness):

  BeginView
  [...]
  imgfile = Untitled
  EndContentInstant
  EndContent

The image filename is indeed untitled.

Now, if the value of imgfile is set to the correct path, it works.

Various alternatives give the same outcome:
- Opening the stack within 3D viewer, than saving the session. 
- Leaving the stack open after saving it, importing it into 3d viewer, then saving the session.
- Working with several stacks or images.

Thank you for your help and for the plugin, which otherwise works perfectly.
