Simple Instagram plug-in for creating WordPress posts from Instagram photos
This plugin is the best choice for my kind of use. There are some improvements that I really like to se (http://wordpress.org/support/topic/post-automatically-tagged-posts-from-users-that-i-follow) but are new features that no other Instagram plugin are implementing.
I'm currently testing this plugin, and it seems like the dev['s] are on their way to being the only ones that support user AND hashtag filtered feeds. Activation worked without a hitch, and if they can get the page feed shortcode to work, it'll be the ultimate, and most flexible, Instagram plugin out there.
