How do I see which game a Steam background is from?
For example this background image:
http://media.steampowered.com/steamcommunity/public/images/items/620/904c34bd20f5a5f5eadb074cce42d2606b266acc.jpg
Answer
The easier way is to look at the game ID:
If you put that number into this url, you go to the game page:
Game 620 on steam is Portal 2.
Keavon also suggested searching for the appid on http://steamdb.info/, which seems to work quite well.
