Or am I going the complete wrong way about this and should just link the poster manually through the manage options in kodi?

When you use standard skin the only way is to replace the mainposter with the animated poster the manual way though manage option - choose art.
There are skins wich can handle animated poster as a seperate arttype, but further support in the related skin threads.

This isn't a support thread, only a content thread. 

 And where is the Support thread?
