Hi yvne,

It doesn't support an explicit 2:3 ratio selector but, if Kodi were to use the poster_path field that gets returned in the primary movie/tv object, they would get to use the "primary" image feature that we support on the website (the requirements to be picked as primary mean that it would be a perfect 2:3).

To clarify, this won't always mean a perfect ratio poster since not all items have a primary set but our rules for choosing the the poster that gets returned in the poster_path are pretty decent. We go down, hunting for the best image in this order:

1. requested_language_primary
2. requested_language
3. en_primary
4. en
5. fallback (highest rated if none of the above conditions are met)

So this has 2 main benefits, first, by using the poster_path field you'll get the same results as the website. Secondly, we've already down all the work trying to find the best image so the client doesn't need to worry about it.

Cheers.
