Hm, the answer seems so simple that I'm almost afraid I misunderstood your question, but here goes...
If you just need to make the image accessible from the windows ssh server couldn't you just scp it there from the computer it's on?
So boot clonezilla on the target computer and tell clonezilla you want to save it to a remote computer using ssh. Or you could save it locally and go to a command line to scp it there manually.
I've used clonezilla before and thought it was pretty generous with the information in it's menu system. Is this question as simple as you make it sound or am I misunderstanding?
