There are two features that allow you to change how your Release/Playlist's main Artwork is shown on a PAGE.
Firstly, you can choose the Size. Select from Small / Medium / Large to increase or decrease the display size of the artwork on the PAGE.
Secondly, you can choose the Alignment. Select from Left / Middle / Right to re-position the artwork of the PAGE. Be aware this will also shift the Title, Artist, Genre & Release Date (if a Release) under the artwork.
