Support of credentials for bigImageUrl extra

[Ra5pi]

It seems like the bigImageUrl message extra is not accepting credentials in the URL like "http://USER:PASSWORD@IPCAM/snapshot.sh?res=low" Without the credentials (and deactivated authentication on the target IP CAM) the feature is perfectly working and rendering the image in the notification.

Is there any way to provide credentials for local IP CAMs to keep at least the minimum basic authentication active?
