Topic: 'No cover image available' on replication server?

Do I have to configure something special to see covers displayed on my little replication server?
Actually, in the higher right corner of a release (where the cover should be displayed) I get only
No cover image available.
I'm sure, that the master MusicBrainz server show this cover.

The 'External link' to the cover at amazon is available for my replication server too and displayed like this:
UK: B00757J98K
What could be the reason for the 'missing' cover?

At the very least you would need your own Amazon API key. Even with that, I'm not sure if there is something else you'd have to do to build up the cover art cache since for legal reasons this cannot be part of the VM. I believe there are some background processes that slowly build this cache for MB; I'm not sure if they are designed for replicated users to run.

Mhhh, I see. Although it is not clear for me, why there should be a legal reason, if a replicated server helps to reduce the number of connections and the cover download to/from Amazon.

But thank you very much for your answer!

The Amazon WS is used to find out the image URIs for each ASIN. It is normal that under such licenses for API access, that you cannot cache & redistribute data retrieved from that service. Maybe it doesn't make much sense for URIs, but I presume the policy is an overall one. Otherwise you could scrape Amazon's data via their WS, package it up and sell it to people - clearly not what the goal of their API is (presumably it is to drive sales on Amazon itself)
