Updating the artist image on your artist pages and keeping this consistent helps to create a visual narrative for a project. It can take time to have these updated so we suggest you start the process at the beginning of your project. Here are the details for updating artist images on ROVI/All Music, which feeds into most digital services, such as Spotify, Deezer, and Google Play.
To change the images on a Spotify artist profile, this should be updated via Spotify for Artists. This allows you to gain control over your artist profile, update images, set featured releases and more.
Here are the banner specs for Spotify:
To change the images on Apple Music, get in touch via Portal > Contact Us, providing a link to download the image (2400 X 2400 jpg). We’ll take it from there. Please note that AWAL is unable to change your artist image until your first release is live.
These take some time to populate in the services and there is no fixed turnaround time, so we recommend getting this in place as early as possible.
