The thumbnail for my new release "Ambient Loops" doesn't have the image I embedded in the body. I embedded an image because it was required in order to post, and I assumed this image would be the thumbnail for the list, but it isn't. Instead, my profile image, very small, is next to the listing and doesn't look very good. You can see how the listing looks here, it's on the second page of release announcements

How do I make my thumbnail not be my profile image but the one that is currently in the body?

Thanks for your help!
