Mike Coutermarsh- Code @ GitHubNot a chrome extension. But would get the job done. I use this for cleaning up my downloads folder for me. Could definitely be programmed to move images to specific folders. Is useful for a bunch of other things as well. I have it delete old files / remove duplicates. Is a great utility.
