First there was FlickrExport for iPhoto, and it was good. Then its developer, Fraser Speirs, asked us whether we wanted him to make a FlickrExport for Aperture, and the answer to that question was also good. Now there is FlickrExport Lite for Aperture, and as a free product, it looks pretty sweet. Previously known at Flickr as the Flickr Plugin for Aperture, Fraser has re-named the plugin and brought it home to be displayed alongside its bigger brothers, complete with a feature-comparison page that breaks down the major features of all three FlickrExport products. If you've been on the fence between using iPhoto or Aperture and want to upload to Flickr, these plugins are where it's at, and I actually learned a few things from this feature comparison page, such as the fact that the Aperture plugin can add geodata before uploading, add tags after uploading and even replace existing photos on Flickr. Looks like this blogger is going to have to give Aperture a more thorough run-through.
Oh, almost forgot: all the FlickrExport plugins have been updated with bug fixes and one big new feature: the ability to set the moderation level on the photos you upload.
