Well this is pretty basic.
This places an iframe in your message when the code is used and pulls information from IMDb to post on your website.
Note: You need to have Custom BBCode Manager installed on your site.
Extract the file -> Go to BBCode Manager -> Import New BBCode -> Select BBCode_imdb and install.
What is does:
Now when someone is search imdb and wishes to post information all they need to look at is the link from tt onwards.
Is the link for Batman: The Dark Knight Rises 2012.
In a post you will add [ imdb]tt345836[/ imdb] (without the spaces) and it will deliver the Batman: The Dark Knight Rises information to the post.
