image should be a text explaining what is in the image. In the photojournalistic world, it is called the W's : Where, When, What, Who, Why.
Oh this is so cool! This is another new tool for taking a static photo and turning it into a story. I love the examples shared in this blog post. I'm getting lots of ideas already and know you will too once you review the material here.
Stipple is the tool and here's a link to an article with examples since the link above does not work anymore: http://stippleblog.com/post/27854001153/10-great-stipple
Now go have fun with your photos!
