Ah, I didn't mean to host an image store on our server. I meant your
tool. And for the review - if you'd lack reviews we can agree that you
just push the patches without any review. That's the agreement we have
for projects that don't have that much attention (e.g. libvirt-php).

I'm terrible with names, so I rather not suggest one.
