[Plugin: Product Review] Placement of the plugin

Hello everyone !

I download the plugin Product review . However it is within the parameters indicate that the plugin can be placed manually in the article with the code:

<?php echo cwppos_show_review(‘postid’); ?>

I search for hours and hours and I still have not found . I want to place it after the first picture of my article.

I do not know if you understand what I mean ??
I’m french , sorry for my english …
