Having looked at them, Tripod UK have no bandwidth limit, and I can use my ISP webspace for the thumbnails without endangering my main website (see first post). I've put in place a general rule that any paid for webspace must be financially self-supporting, and as I have no plans to make money from Poser, I guess that rules commerical space out for any Poser site. I will have to redesign the page layout to appear below the Tripod adverts, but I can live with that, and they do disappear fairly quickly.
