Webcam image pull (generic camera) alternative needed [SOLVED]

I am looking into a way to show the following webcam images within a hass group in the dashboard:

http://www.svz-bw.de/fileadmin/templates/vizbw1/kameradetail.php?id=S291

but the image url has some parameters attached, which I don’t understand and which break the image pull via the generic camera module. Because I can’t extract the raw image url.
Is there a way to get the whole frame from the url above shown in the dashboard instead of the image only?

regards,
Karsten

Although the panel_iframe implementation does not scroll correctly, I’ve used these to accomplish that task. The preferred mosaic view doesn’t seem to be achievable with URL refferrers and JavaScript built pages.

Anyhow the quick(er) lookup up of traffic cam works now :wink:
