I noted that FAQ item previously. My web-hosting provider has not answered my inquiry about "Hotlink Protection" but I see other people using the same service using simpleviewer successfully.
As for the Casesensitive names, i also don't think that's the problem.... Wait.... Eureka!
Thank you. I had checked and checked this but appreciated your response so much I triple-checked. My ftp client shows imageData.xml as imagedata.xml (locally and distant). I had to go to the folder in explorer to note the difference. And that was the problem.
Thanks a million.
