Image field does not display on embedded node

This module looks like the perfect solution for what I'm trying to do, but the documentation is lacking, and I'm having a difficult time getting to work as advertised.

I have a node type "image", so that I can attach extra fields for date, location, exif data, etc. I'd like to embed these nodes into the body text of other fields, and node_embed offers a way to specify the format (such as how the image is presented with its title, caption, etc.).

I installed the plugin, configured the view for selecting a node to embed in the text, and set and used the "node embed" display type, with the image among the fields to display. So far, so good.

Everything seems to work... I get a field title for the image field if I ask for it, I get a link to the image if I ask for it, but there is an empty string where the image itself (the tag and all of its parameters) should be.

Also, where is the "default template" for an embedded node if I don't specify one? Perhaps the module should come with a well-documented template that we developers could modify to our needs. Or if it does, where is it?

For the record, I'm using a subtheme of adaptivetheme, but I've tried Stark, Zen, and Bartik, all with the same result: no image field. Am I missing something, or is this a bug?

Thanks for your attention.
