I created this a couple of weeks back but didn't post it here (as we don't have a Neopets section). However, other people are using it to post the answers to their respective forums, so why not this forum, right?

It's set to run on a cron every 10 minutes. It:

  1. Checks Neopets for a new mystery pic
  2. If it finds a new one, it attempts to solve it.
  3. Once it solves it, it stores the solution in the database.

It generally solves it in around 2-3 minutes (it has to cross reference the picture with 150k images). As it's set to run every 10 minutes, at most you're going to get the answer 15 minutes after the picture comes out. If however, we use the law of averages, you're going to get it around 7 minutes after it comes out. It's more than enough time to get that gold trophy.

Happy hunting.
