Better to use id from tmdbid dont prefer imdbid, all movies dont have string in api v3 for fanarttv with imdbid...
Or add string if webart is emty to try with tmdbid
Can you check this isue....

That is really not true, the fanart.tv API is perfectly capable of handling the imdbid which is a string.
In fact, I just tried with the example you gave me and it gave me the images just fine.
The IMDB ID is used for ALL lookups so it can't be ignored, it's like that in the entire script.
Maybe the IMDB ID is wrong for the movies in that widgets ?
Do you know if the items in your widgets have the imdbid (ListItem.ImdbNumber) set ?

Please try to lookup that id on IMDB to check if the correct movie.

Movie "Storks"
