Ahh right, we convert links to images to actual links so users in iTunes application can click them. Apple is not displaying the links in the same way on the online version of iTunes, which I see is a problem.
To turn this feature off, go to PowerPress menu > settings page in your wp-admin. Select the iTunes tab, then browse to the setting titled "Enhanced iTunes Summary". Turn this feature off. Turning this feature off will remove links to web pages and images from your iTunes summary. The only downfall to this is that these links will no longer appear when a user reads your summary from within the iTunes application.
