Feed Validation Troubleshooting

Hi there,

I’m having troubles validating my feed and can’t seem to track down the issue – everything looks straightforwardly ok but there’s a error with the image. Link to feed:http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fintuitiontosucceed.academy%2Ffeed%2Fpodcast%2F

Error: This feed does not validate.

line 26, column 1: href must be a full URL: http://www.intuitiontosucceed.academy/wp-content/uploads/2014/09/Intuition2SucceedPodcastIcon03rgb.jpg (2 occurrences) [help]

I’m setting up a podcast through Blurbrry Powerpress and haven’t run into this issue before. I’ve tried multiple files, copy/pasting the link in to the Artwork area – keeps coming up with the same issue. Any insight is appriciated.
