[Observium] Publish single graphs without authentication

Hi,

I am looking at Observium as an alternative / addition to Cacti and it looks really nice so far.

One thing I do with Cacti is publish single graphs of bandwidth on core routers and switches to websites (or wikis), so that other people can see that current usage very fast without having to access Cacti. This works by giving a guest (means: no login) read access and then just using the URL for the graph (e.g. .../graph_image.php?local_graph_id=330).

The last part is as easy in Observium (../graph.php?type=port_bits&id=150&height=200&width=600), but I don't think there is an easy option to do this without authentication.

Any idea on how to accomplish this?

Thanks
