I'm very new to api and I'm using javascript to build a movie recommendation site.

Can someone please tell me how to return an image url from a given movie name or id?

Given a string (ie: "The Dark Knight (2008)") what's the best way to go about getting the themoviedb "id"?

A sample code for either of these actions would be very helpful and much appreciated! Preferablly using either of the 2 javascript api's: "tmdb-js" (https://github.com/EtienneWan/tmdb-js/) and "themoviedb-javascript-library" (https://github.com/cavestri/themoviedb-javascript-library/)

thanks!
