I've committed support for showing the filename if the tag information isn't available.
Nope. The notification plugin used by the N900 doesn't support being given an explicit path to an image. A workaround would be to get the image, resize it (multiple times for the small notification and for the larger notification), put the resulting images in the folders that the notification plugin does look for images and hope that we don't encounter a race condition. Doing all this, BTW, would make the N900 rather slow when pressing the "next track" button repeatedly.
@tuminoid I'm looking at https://garage.maemo.org/pm/task.php...roject_id=2599 . It wouldn't take long to add statusbar applet functionality (I've written a few of those already =)) to the notifier. This is what I've come up with: The album art is real, is from MAFW and resizing it is no problem. Ignore "Example Title" and "Value"; you already know that we can get those filled in by MAFW.
