Not a bug?

Hi Keith - yeah that is expected, MoI does not try to bake the image itself directly into the .3dm file. If you want to have the background image show up you will have to bring along the image file too.

When you move the file to the other machine, you can have the image stored in the same folder where the .3dm file is at and MoI should find it when you open the file up.
