Description of your issue, suggested solution and other information

I'd like to request a feature please, the feature is --write-artwork for crunchyroll, for example if you type youtube-dl.exe --write-artwork http://www.crunchyroll.com/naruto-shippuden it will also download the artwork from the right hand side http://img1.ak.crunchyroll.com/i/spire1/958243dc68ae929a6b9cb834165112471456969325_full.jpg

Hi, if this resquest is aligned with the project guidelines and milestones, I would like to adress it.

Implementing this feature requires introducing a new playlist level meta field first. Second, there is no point in this option at all - there is already --write-thumbnail exists.

[BridgeUK]

@dstftw --write-thumbnail only downloads the thumbnail for the episode, by using --write-artwork for a playlist it would download the artwork for the playlist.

[dstftw]

Once again: there is no need in another option. Existing one should just write playlist's thumbnail.

[BridgeUK]

@dstftw when I tried --write-thumbnail earlier it only downloaded the episode thumbnail not the playlist artwork.

Did you even read my posts? It's not implemented.

[BridgeUK]

@dstftw my mistake sorry, when you said "Existing one should just write playlist's thumbnail" I thought I had missed something on my end when using the command.

[BridgeUK]

@dstftw to me --write-artwork would be a very useful feature.

@mcerdeira are you able to complete this, please?

Thanks!

if anyone has the time to complete this it would be most appreciated, thank you very much :+1:
