I'm trying to fetch the excerpts for next and previous posts but can't seem to figure out how. next_post_link() doesn't seem to offer the excerpt as an argument, and get_next_post() has no documentation, so I am unsure what I can pass to it. Seems like that should be the one to use.
What I'm trying to do is have the next and previous posts available as links via the thumbnail I insert into the excerpt for each post, so I'll have images as links instead of words. Thanks for any suggestions.
