Hello I don't know why but I am unable to get the cover art for movies using NZB.su.
I also have usenet-crawler and the sexy movie layout works great with that.

Is this an issue with NZB.su api's or do you just need to add support in your app?

Thank you
NZB.su needs to add the coverurl parameter in their API results. That's what nzb360 uses to grab the cover art, and it's included in the newznab api spec. NZB.su just needs to support it.
