That doesn't stop anything. There is nothing stopping me from writing up a spec that says "Put an annotation like this in your gemini file and with tools supporting this spec addition, you will see an image embedded". For non compliant browsers you will just see plain text and for new extended browsers you will see an inline image.

I agree that this is possible and that the Gemini project might be futile because of this.
