Just to see if there is an easier method, I checked with AW2000 tech support.
The only method to generate a Preview which you can email to a client is to use the "Preview" right before the item lists on the Lister window itself. That way the images are uploaded and the generated page already has the URL's correctly written. You should be able to save it and send it.
I am gonna give it a whirl and see what happens. You may get an email from me!
