Re: Setting iTunes album art with ScriptingBridge

Thanks for the reply, I eventually solved this by resorting back to
AppleScript for the artwork stuff, ugly but it works...

As for posting source to the list, thanks for the tip. Some lists
frown upon it so I have been using Pastie but I will paste small code
samples inline from now on.

Cheers
Dave
