About time... 500px plugin for Aperture :-)
 
  Been looking for a quicker way to upload photos to 500px for a while now, even considered coding one myself, however not being a OS X developer, this was not going to happen any time soon.   Works great, recommended!   You can download it here:   https://github.com/iKenndac/500px-Aperture-Uploader/downloads   Instructions for installation as per the ReadMe :   To install the plugin, place it in ~/Library/Application Support/Aperture/Plug-Ins/Export. This folder tree may well be missing on your Mac - if so, just create them. Note: The Library folder in your home folder is hidden by default on Lion - you can get to it by holding down the Option/Alt key and choosing "Library" from the Finder's "Go" menu.   Thanks to Daniel Kennett, hopefully 500px will embrace this on there Apps  page.   UPDATE: Author has released a new version !
