1. If I go from one artists to another (or, say, listen to an album with multiple artists), it takes sometimes quite a while before the fanart for the new artist appears. Like, if I go from a song with Moby to a song with Coldplay, it displays Moby pictures while I listen to Coldplay... You know what I mean?

The slideshow won't change to the new artist until there is at least one image downloaded. If you have a slowish internet connection, the first image is particularly large, or you are filtering out non 16:9 images from last.fm, then those things can cause the delay. You'll find the change over pretty fast for locally cached stuff.

2. Would it be possible to also have it working with www.fanart.tv? Last.fm and htbackdrops especially are just fine, but it wouldn't hurt to have one more source to download from, now would it?

I've been thinking about adding that. At first I was waiting for the new fanart.tv to release with the new API. I'm pretty sure that has happened, so now my excuse is I haven't gotten inspired to add it. It's on the list though, I promise.
