iFlicks 3.4 and up supports automatic download for all common artwork types. This includes:
- Wide Artwork as used in the TV and Music apps
- Posters as used in iTunes for Movies
- Square Artwork as used in iTunes for TV Shows
By default iFlicks uses the artwork type best suitable for your environment. This means it defaults to wide artwork in macOS Catalina and posters / square artwork on earlier versions.
If you want to change the defaults, there is a sample rule available in iFlicks which you can update and edit according to your requirements.
