Make image submission/conversion/display work
Make basic image submission process work.
This is actually a multi-step ticket but I think it's appropriate
to lay it out in one.
Basically have views to guide the user through submitting an image
and registering it for conversion. Then convert it w/ the
celery/whatever conversion system we have yet to write, then have
it actually be available as something to view on a basic page.
This ticket doesn't cover the "final" adjustments of what
displaying an image will look like, it just needs to make this
possible and viewable from start to finish.
