get_images raises ValueError when parsing uri "spotify:directory"

[kingosticks]

Iris causes this straight away when you go to browse.

I am getting the same issue:

If someone wants to fix this, they can just handle the exception and return an empty response. We don't need to support returning images for arbitrary browse directories, I think this is a weird thing for a client to request.

[djmattyg007]

It could be analogous to album art?

[kingosticks]

I'm talking about virtual directories like the ones in the examples I provided above. What would we return for spotify:featured:playlists, for example?

[djmattyg007]

Right, that doesn’t make sense.
