the only 3 viewers I know of read the obj file but not the cr2, poser character format as in the one sharecg uses as an option for 3d model uploads .similar to this one http://www.tucows.com/preview/605254/3D-Model-Viewer

 I guess you could pose the character, export it as an obj in its posed position and then view it in the viewer.

But if you have poser, I'd just make a small animation of the pose and loop it, for example just rotate the posed character at the last frame, and then render a preview animation. You can add comments to it in a simple movie editor by using the subtitle or title options
