Hi.
In future fanart will be stored in Database, but for now, local fanart is used directly from source without any caching.
This definitely is not the case, I'm absolutely sure. MP2 is using local fanart only. At least if the drive on which they are stored is online while running MP2 client. I can hear the HDD spinning up when fanart is about to be shown. If the Drive (NAS in my case) is offline, MP2 uses downloaded fanart if some is available (not always the case).Currently these files are ignored by MP2
