Image when no book cover is available

Hello @xbhy
Thank you for your query.
No, there is no direct way to change that cover image but you have pointed an interesting feature what we should consider for future update.

hello @xbhy
Great news! We just added an option to set a default book cover image.
You can find it in the general settings page.
