First off, links posted anywhere on the site need to be coded to prevent take-downs. The software you describe is your choice. I would not.
Now all you need to do is refer to the rules I posted above to make a post. Find the right place in the links forum and post away. Above the message box you with see boxes with selections. Make sure you put links in code tags. Images go in Img tags. IMBD url goes in URL tags.
The link above tells you what you must have, rules usually do that.
