Thanks for the tip. I tried it, but to my best understanding it didn't
reveal any secrets. What I could see was that the call returns a PICT
image with data, but that much I knew already. What bugs me is that
both the NSAppleScript and the ScriptingBridge approach are supposed
to return the exact same results, yet
[[[[NSAppleScript alloc] initWithSource:@"tell application \"iTunes\"
to return data of artwork 1 of current track"]
executeAndReturnError:nil] data]
works, but [artwork data] doesn't... Oh well, I'll keep trying.
