Podcast Site Manager error: The feed does not contain a valid podcast image. Podcast images must be at least 1400 x 1400 pixels.
I'm trying to upload a new podcast and I keep getting the same error: "The feed does not contain a valid podcast image." Podcast images must be at least 1400 x 1400 pixels. I've checked my image and it appears to be 1400x1400. http://downloads.cdn.sesame.org/podcast/Sesame+In+Communities/iTunes_Icon_RFS_ENG.png
Any help would be appreciated.
