a small image glued to the save wings3d object

Well Yes Sir, I'm sure they'll get right on it! .........
Um actually I'm not sure this is possible. As I understand, the root program of Wings3d is hard coded C from the '90s, and hasn't ever been changed. The interface is done in Erlang, and these Great Guys developing are stuck with the Erlang side. They've done a great job adding customization and better access to the interface, and are able to script-string commands together to add functions like Sculpting and Tweak. They've even been able to re-build the package for 64-bit use, but it's still the old core program. I had a similar request a couple years back to be able to add several images in the texture folder, for use with the Environment Map Shader after seeing what was being done with Sculptris and Zbrush. But I was told then the same thing, and that the Grandcanyon.png image was named in the hard-code. You can keep several images in that folder, and rename them as you need them, but this all has to be done Manually. And further it's expecting a 512x512 PNG image.
On the other hand, Wings3d can take a Snapshot, does have some imaging tools and can save an image, although I'm not sure about the .ico filetype. So most of the tools are there ......
