Data URI scheme

OK, browsers must support it ... but my question is another :
Does the editor implements an image upload converting the stream as:

<IMG SRC="data:image/gif;base64,R0lGODdhMAAwAPAAAAAAAP///ywAAAAAMAAw
   AAAC8IyPqcvt3wCcDkiLc7C0qwyGHhSWpjQu5yqmCYsapyuvUUlvONmOZtfzgFz

?
Thanks.

I am sorry
... maybe that:

converting a file into a data URI is not a task for THIS HTML editor

Excuse me ... but the only way to obtain the result is:
1) Click on the "Image" button
2) Click on the "Update" tab
3) Select a file on the local filesystem and click on the "Send it to the Server" button
... at this point, checking an hypothetical "Embedded" option, the editor should process the image using a standard base64 encoder ...
4) As result I have in the image URL the encoded content (instead of a relative, server-side, position)
... How I can obtain the same result in an alternative way ?
The upload is a CKEditor internal task !
My host application can manage the conten only later (... too later ...!
Regards.
