<br>
it's disappointing that this is still an issue.<br>
We're currently using OpenStack Ussuri with Ceph Nautilus (we plan the <br>
Upgrade to Octopus soon) which works fine without enabling <br>
show_image_direct_url. The same goes for Victoria and Octopus (one of <br>
our customers uses this combination).<br>

<br>
I'm also wondering in which case the location contains credentials, I <br>
haven't seen that yet. Depending on how your cloud is used (is it a <br>
public or private cloud) maybe enabling the option is not that big of <br>
a risk?<br>
<br>
Regards,<br>
Eugen<br>
