Using Markdown, how do I center an image and its caption?

Question

I want to end up with:

Hello there!

      
      This is an image

Hi!

Where the image and the text This is an image

Answer 1

In Mou (and perhaps Jekyll) this is quite simple.

-> This is centered Text <-

So taking that in mind you can apply this to the img syntax.

->![alt text](/link/to/img)<-

This syntax doesn't work for Markdown implementations that implement only what is documented on Daring Fireball.
