The original source for WfW 1.1a was open sourced (I realize that doesn't mean there isn't copyright, but it's unlikely to be the reason that there are no pics):
The license isn't really open source. It's more like source available. Non-commercial use only.

says
You may use, copy, compile, and create Derivative Works of the software, and run the software and Derivative Works on simulators or hardware solely for non-commercial research, experimentation, and educational purposes. Examples of non-commercial uses are teaching, academic research, public demonstrations, and personal experimentation. “Derivative Works” means modifications to the software, in source code or object code form, made by you pursuant to this agreement. You may copy and refer to any documentation provided as part of the software. You may not distribute or publish the software or Derivative Works. You may not use or test the software to provide a commercial service unless Microsoft permits you to do so under another agreement. You may publish and present papers or articles on the results of your research, and while distribution of all or substantial portions of the software is not permitted, you may include in any such publication or presentation an excerpt of up to fifty (50) lines of code for illustration purposes.
The point of open source is to address and concerns around copyright. And this source is not open source by the definition most people use when they refer to “open source”. It’s still proprietary but source available.
However I will say, this source is unlikely to be useful to anyone beyond academic curiosity. So for the purposes of this project, the source license is “good enough”.
