First album played has become the default art displayed

Hi All,

The art of the first album I selected to play when first installing Volumio in my RPI is now the defaurt art that appears whnever I navigate to the browser. Actually its a pretty ugly cover, and I only selected it as a test. How do I get rid of this? Can I specify another album cover or control this behaviour in any other way?

RPI model 3b, operated headless over wifi, Volumio version 2.657

Thanks in advance for your help!
