Podcast Artwork Requirements
I know that the range for artwork requirements is 1400x1400 through 3000x3000 pixels.
However, I heard that there are other requirements in order to be eligible to be featured in iTunes spotlights, such as "most popular" or "staff picks". What are those requirements? Can the aspects be asymmetrical (i.e. 3000x28000) and still be featured?
Thanks!
