> > name of the tiddler that you'll want them to appear in.

This assumes that the image is to appear in only one tiddler.  What if
you want the same image to appear in more than one tiddler?  Also, how
will you control placement *within* the flow of the tiddler content?
What about image display options like floatleft [<img[filename.jpg]],
floatright [>img[filename.jpg] and linked images [img[filename.jpg]
[URL]] ?  How will those be specified?

It seems like you are proposing to embed local path information within
the ViewTemplate.  The purpose of the ViewTemplate is to control the
*layout* of the rendered tiddler (and also sometimes to trigger macros
that have side effects, so that programmed actions can occur whenever
a tiddler is displayed). To define configuration values that are used
throughout the document and need to persist across sessions, you
should store them as slices within the SystemSettings tiddler.  (see
http://tiddlywiki.com/#PersistentOptions)

This forces you to have multiple images with the same name (albeit a
different numeric suffix).  This makes it really difficult to manage
those image files within that directory, without needing some kind of
image viewer to differentiate the files.

It seems to me that, except for your specific, narrowly-defined use
case, most people will still use the "common/manual" method of
embedding images.
