You have linked to a page with a stack of currently live stream thumbnail…
Both the stream thumb and channel profile can be fetched from the streams kraken API endpoint (if live) or for just channel/use logos the user endpoint
- Profile logo is the logo key of https://api.twitch.tv/kraken/channels/barrycarlyon
- Thumbnail would be in preview key of https://api.twitch.tv/kraken/streams/barrycarlyon (choice of sizes) BUT ONLY If I was live (which I’m not)
So in summary, for the channel(s) you want, poke the Twitch API and then read the response
