Big news about your iTunes cover art. We ‘ve just been notified that Apple has gone big — I guess you could say the “big Apple.” Apple has notified us that new iTunes album art specs have a minimum image size of 1,400 x 1,400 pixels* (which is what it has been in the past) to a maximum 2,048 x 2,048 pixel size cover art in JPG for podcast feed and podcast episode images. Apple is still recommending the 1,400 x 1,400 size, but, hey, a little flexibility is always nice, right? We’ll be updating the plugin specs on our site, but we wanted to let you know ASAP.
Apple is “not” recommending you save your image art in .png (portable network graphics) format, but if you can’t resist .png needs to be RGB (red, green and blue color model) only. That’s straight from Apple folks!
* Specified image sizes are in pixels — a picture element for digital imaging. The size of the image file on a disk is expressed in terms of “kb” (kilobyte) or “mb” (megabyte).
