I am looking to impliment something like this, and this is a great start.... Question: What about images? If my Body post includes an image embed will that image become the default blog post image? Will it be uploaded to steam and saved as if I pasted it into the post window on steemit.com?

If not how could I extend this example to add an image upload for the primary blog image?

Also how could we add more tags 4 more other then the primary one used as the category? Any info you could share would be great!
