You can learn informally by participating in graphic sites like Renderosity, Art Station, Daz3D or DeviantArt. 

These sites have graphic communities, forums and galleries where you can play and learn. They're not specifically geared towards games, but it will teach you graphic skills over time, and then it's up to you to hone those skills for games. There are many of us who use the art and content from those sites in our games.
