Using Aviary for "Post Image"

I’m using GF to build a form for user submitted Posts, and would like to use Aviary to allow users to edit the images they’ll be uploading as “Featured Images” for their posts.

Is this possible and if so, how?

I’ve made an “out of the box” attempt, but the image doesn’t attach to the post.
