My question is probably an insane idea, however, it's very valuable when I write code for educational purpose.
Especially when the code is relevant to math and physics, images inserted in comment are more convenient and articulated.
Until now, I can't find a way succeed to insert a true image into comment, not C# nor python or any other common programming language or IDE.
Using tools that convert images to ASCII image is a workaround but less precise.
Any idea is appreciated
There is an example here that extend the Visual Studio 2010 editor: Image Insertion (but it's tied to Visual Studio, not a generic solution)
