Having the same problem again. My image is 1600 x 2100, but it's not repeating more than once. When I have lots of items in one shopping category, and the web page is long, the image is running out, and I'm just getting a white background.
I've tried changing the repeat image to 1600 x 4200, but that doesn't display at all.
http://www.shamrockshirts.com.auCould you please tell me how to fix it? This was working perfectly last week, and I've changed nothing since then. Very very frustrating.
