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.

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.

Sounds nice. Thanks for the answer. However, how about using the "fallback" folder for when a new artist's photos are in the process of being downloaded? That way, we could create a folder with only one picture in it (be it black, our XBMC background etc.) and have that display, right until the moment when the first image gets downloaded for a new artist? I'd much rather like that, instead of having it display pictures of the previous artist.

I'm not that much in to code, but something tells me this wouldn't be too hard to implement, no?
