I don't know if this is something that GGG is interested in providing, but Riot with Legends of Runeterra provides a full Streamer kit at the bottom of their media page on their website. I feel like this is a really great resource that potentially GGG could provide to aspiring content creators.
Anyways, here's the link if you're interested - https://playruneterra.com/en-us/media/
Yeah potentially this would be very good. At the moment we email them to people who ask but that's a better scenario.
Thank you for the effort, but honestly, there are going to be thousands of people wanting this as their wallpaper. I think you guys are going to be overwhelmed with the requests processing. I would suggest just putting it somewhere publicly available, the higher resolution the better, for everyone interested to be able to grab and resize as they see fit.
Yes, I was referring to the press kit we send out to a select number of people. (It doesn't include that image as a wallpaper).
