podcast verification error message
I am trying to upload my podcast from Podbean. I'm getting this error "Podcast artwork must be between 1400 x 1400 and 3000 x 3000 pixels, JPG or PNG, in RGB color space, and hosted on a server that allows HTTP head requests."
My image is exactly 1400 x 1400 pixels, 52 KB in size. Can you tell me what I'm doing wrong?
