an image processing use case for wsdl

hi,

I mentioned some of my concerns this morning about wsdl's support of REST.
I'd apprecite
any feedbacks on the follwing use case:

Suppose we have an image processing WS. All images are droped to this URL:

http://www.foo.com/image/incoming, using POST.

All clients will then get processed image from the following URLs:

http://www.foo.com/image/$client_id/

after, say, 10 minutes from droping the images.

The question is, how do we use wsdl to describe this service?

Hao
