The 9210 WAP browser does not appear to make requests for images that are on a different domain to the page containing them.
For example, if http://www.mypages.com/index.wml contains <img src='http://www.myimages.com/image.gif'>, the request is not made.
The "progress icon" does not even spin, and I can confirm that no request arrives at the WAP gateway.
Absolute URLs to the same server as the page work - so that's not the problem.
Anyone else seen or solved? Or is it by design?
