virtualbox.org

I've tried running Tails in VirtualBox, and it gives me an error that it's an unsupported storage format (it's an IMG file rather than ISO, and I don't know whether that has anything to do with it, but I don't know where to get an ISO of it). How can I get it to run?

ISOs are available here: https://tails.boum.org/install/index.en.html

Thanks! Somehow I must have missed that before.
