Station favicons

Per default you'll get a small logo / icon for any station with a homepage link. They're automatically fetched and displayed as soon as you play a radio entry.

This functionality meanwhile resides in a plugin. It's available in the 🔌 Features configuration tab. You can disable it as whole if unneeded. Most configuration options are now collected there.

Some channels (Jamendo or Radionomy) provide small album previews or banners (Punkcast) even. Whereas normal favicons are just 16x16 pixel images.

Downloaded image files are meanwhile all sanitized (internally converted to ensure they're really image files). Albeit that's not strictly necessary for modern Gtk versions. (But better safe than sorry). Images are kept in the ~/.config/streamtuner2/icons directory.

Configuration options

Load favicons on playing: When starting to play a station, its homepage favicon is automatically downloaded in the background. It's even displayed right away as soon as it's there. You can also have a whole category/genre list updated right away per menu command Channel ▸ Update favicons....
Homepage googling: When playing a station that doesn't have a homepage entry, streamtuner2 tries to google the station title. The found URL is then used/kept as station homepage. This isn't super exact however, so you might end up with homepages and icons from Wikipedia, Twitter, Facebook or something for generic radio station names. (Btw, station titles like www.mymusicstation.com are automatically mapped to homepage URLs already.)
Use Google favicon service: Downloading favicons directly from station homepages can sometimes be a little slow. Which is because it requires to inspect the homepage itself first, and then uncovering an image resource. The Google method instead uses http://www.google.com/s2/favicons?domain=www.example.com to fetch a PNG icon right away. Which is often faster. You might want to disable this for privacy reasons though.
Omit placeholders: Oftentimes the Google favicon service sends back a placeholder icon (a blue mini globe), which doesn't look very interesting. So you might want to disable those. (They're still downloaded, but just not saved in the cache directory.)
