IMAGE in Sitemap not display webcam from bayerninfo.de

Hello,

I integrated several local cameras and also webcams into my sitemap.
Unfortunately, the following camera can only be integrated via Webview but not via Image.

All other cameras (from local and other webserver) can be integrated via Image.

Webview url="http://www.bayerninfo.de/webcams/images/a3frankfurt-wuerzburg/192.168.129.11.jpg" height=11

Can someone tell me why that do not work?
