Cover Art on Subsonic 4.7, Ubuntu 12.4 LTS, Fedora Core 14

[Luqman]

Hi,

I have 2 machine with 2 different version of subsonic.
Machine A, Fedora Core 14 + Subsonic 4.6.
Machine B, Ubuntu 12.04.1 LTS + Subsonic 4.7.
Both of this machine accessing the same NAS for music files.

Actually, i want to "Power Off" machine A because it using old hardware. I have a new machine (Machine B) with new hardware inside. also I've put new OS and the latest version of subsonic.
Everything goes normal and works fine, until i found an error or problem on Machine B.

Problem:
- When I update a cover art, it's doesn't updating the thumbnail. or it's displaying the wrong cover art.
- Then I try to power on Machine A, just want to make sure that it's have the same cover art. But, it's not. Machine A works good. Everything that i've already done before, like update cover art, put new cover art on Machine B, it works and displaying just like what i want on Machine A.
