Emitted Object Color from emitter material

Hi guys,
I have a plane mapped with an image. I would like to emit some particle object having the color of the image in that point.
I have no idea what is the way.
Do you have any suggestion?

You can find some info on doing this here: http://blendersushi.blogspot.fr/2012/12/cycles-particle-info-node-basic.html

Thank you KWD! Super useful!

I post the image that I make using your great link! Thank you!
