Responding to Philippe Verdy:

Well, if the format became accepted as part of Unicode then appropriate applications could well be produced that would interpret the format and display an image in the desired place.

The format is just at present a basic suggestion. Rather than just state what you consider what I have forgotten and dismiss the format, how about joining in progress and specifying what you consider needs adding to the format and perhaps suggest how to add in that functionality in the style that the format uses.
The two questions that I asked in my response to a post by Mark E. Shoulson are relevant here.
Suppose that a plain text file is to include just one non-standard emoji graphic. How would that be done otherwise than by the format that I am suggesting?
What if there were three such non-standard emoji graphics needed in the plain text file, the second graphic being used twice. How would that be done otherwise than by the format that I am suggesting?
> At least with HTML5 they don't try to reinvent the image formats and there's ample space for supporting multiple images formats tuned for specific needs (e.g. JPEG, PNG, GIF, SVG, TIFF...) including animation and video, and synchronization of images and audio in time for videos, or with user interactions. They are designed separately and benefit from patient researches made since long (your desired format, still undocumented, is largely under the level needed for images, independantly of the markup syntax you want to create to support them, and independantly of the fact that you also want to encode these syntaxic elements with new characters, something that is absolutely not needed for any markup language)
Well it is undocumented apart from posts in this thread because I have put forward the format for discussion. A pdf document for consideration by the Unicode Technical Committee could be produced and submitted if there is interest in the format, the content of the pdf document perhaps including suggestions from this thread if any such suggestions are forthcoming.
> In summary, you are reinventing the wheel.
Well, this is progress, producing an additional format for expressing an image for application in various specific specialised circumstances.
