The Android and iPhone app Bump has been updated to extend single-touch photo-sharing beyond phones to include your computer as well. From within the free app, select the photos you want to transfer then head over to bu.mp and tap your spacebar with your device to initiate the transfer. The files will then pop up on your browser where you can download or share them with friends. No additional PC software is required, although you'll need to use Chrome, Firefox, or Safari with location tracking enabled for the feature to work.
