Tag characters and in-line graphics (from Tag characters)

There's no advantage because what you want to create is effectively another
markup language with its own syntax (but requiring new obscure characters
that most applications and users will not be able to interpret and render
correctly in the way intended by you, and with still many things you have
forgotten about the specific needs for images (e.g. colorimetry profiles,
aspect ratio of pixels with bitmaps, undesired effects that must be
controled such as "moiré" artefacts).

You don't need new characters to create a markup language and its syntax.
Today the world goes very well with HTML(5) which is now the bext markup
language for document (including for inserting embedded images that don't
require any external request, or embedding special effects on images, such
as animation or dynamic layouts for adapting the document to the redering
device, with the help of CSS and Javascript that are also embeddable).

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)

In summary, you are reinventing the wheel.
