So, I just discovered the "Header Image" and "Thumbnail Image" in the C5 (5.6) blog entry composer. Really cool. What's not really cool is I cannot figure out for the life of me how to call the images it creates in my blog_entry.php file. I've managed to customize the size to what I need, I just can't figure out how to actually echo it in the individual theme. I've looked over the Forums to no avail (sorry if it's there, I couldn't find it.)

My theme has a place for a "featured image" that looks like this:


I'm trying to figure out the path to the file to put it in there.
Any help would be huge. Thanks.
