The episode artwork is what you have to upload along with your show every time. Your episode artwork can be the same as your general artwork or you can change it time after time especially if you have different guests on the show. Radios might add their logos and the broadcasting times and publish it on their websites and social networks. Please keep this in mind when you are creating the artwork.
The episode artwork must be square and a minimum size of 1500x1500px and the maximum size is 3000x3000. The file size must be under MB so you need to keep the resolution on 72dpi.
