Cover Thumbnailer (For Linux)

One of the fun things working with a vast music collection, is the ability to integrate the Cover Thumbnailer app. 

[In conjunction with the parent article: Linux Audio Tools.]

The Cover Thumbnailer application is an add-on to Linux, and works specifically with Cover Art, and with your native File Manager. If a music album has cover art within, then the File Manager can render it for view. The cover art image becomes the image seen on the folder object icon. See the screenshot (third image) below. But first, you’ll need to install it.

Install

sudo add-apt-repository ppa:flozz/flozz
sudo apt-get update
sudo apt-get install cover-thumbnailer

Once installed, you can gain access to it from: Menu > System > Preferences > Other > Cover Thumbnailer.

Usage
The screen will look like this:

  1. There is not much to change here, but you will have to specify which folders are to be included.
  2. Go to the Ignored tab, and add in the folders to never ignore. These should be your music related folders on your local machine.
  3. Click OK to save.

Once the Cover Thumbnailer is configured, your File Manager will look something like this:

Points to Note

  1. For cover art to be displayed within your File Manager, the file names will need to be set to: folder.jpg or cover.jpg.
  2. Front.jpg or the use of any other name will not display.
  3. The acceptable image formats are: JPG and PNG. GIF, TIFF or BMP will not work.
  4. The dimensions of images are to be set at 150 pixel (width and length) or higher. Anything less will not display.
  5. Cover art will display by default for folders located on the Local Machines.
  6. Folders on NAS Drives will not be displayed (see note below).

Point about NAS Drives
You can view cover art on folders on NAS Drives, but only if they are mapped back to the Local Machine through an FSTAB entry. This is beyond the scope of this document, but yes, if a NAS Drive is set up in the ‘fstab’ file, any folders with cover art can be viewed locally.
