iTunes won't accept my validated RSS feed
Hey folks, I've scoured the web, and I think I've exhausted all of my resources (and energy), so this is my last resort. I'm attempting to publish a podcast and I've ensured that the RSS has been validated. I'm using PowerPress (Blubrry) on a Wordpress site to generate an RSS feed from a category page on the website. I've also made certain that the artwork is within specifications (2000 X 2000 RGB JPG) and all of the files for the site are hosted on BlueHost.
Each time I try to submit the RSS feed to iTunes via "Publish a Podcast" I receive the following error:
"Podcast cover art 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"
Here's a link to my RSS: http://gracechurchrolla.com/category/message/feed/
And here's a link to my image if it helps: http://gracechurchrolla.com/wp-content/themes/themetwo/media/title_image.jpg
I've tried Feedburner as well, and several different configurations with PowerPress. I've tried hardcoding the image tag into the header of my site, and I've tried uploading a 1400 X 1400 px image instead. No avail on any counts.
Any ideas? Your help would be greatly appreciated!
