3d modelling from 2d image

I need to know that is it possible to model a 3d image from a 2d photgraph image in blender so as to create a 3d model for animating???

Yes. Set up your photograph as a reference image and model your 3d object. There are a number of good tutorials out there to teach you how to model. I recommend starting here: http://cgcookie.com/blender/cgc-courses/blender-basics-introduction-for-beginners/
