WordPress Plugin: Flickr Insert
Here’s another WordPress-Flickr plugin that is basically the same as Flickr Tags but the behavior is completely different. Instead of placing the photos from Flickr in the post when the post is displayed, the plugin now does the same when the post is published or updated. It also retrieves thumbnails from Flickr and stores them on your own server, so later, when the post is displayed, thumbnails are taken directly from your server.
This could really increase speed if you’re using a lot of Flickr photos.
