NOTE: This plugin is far from fully baked. You will need to be comfortable 
with template hacking in order to customize this plugin to look good with your 
theme.
Photos Flickr is a WordPress plugin I wrote around <a href="http://www.dancoulter.com/" rel="nofollow ugc">Dan Coulter</a>‘s <a href="http://www.phpflickr.com/" rel="nofollow ugc">PHPFlickr</a> library, which in turn accesses 
the <a href="http://www.flickr.com/services/api/" rel="nofollow ugc">Flickr API</a>.
My approach has been to write functions that you can call from a page template 
to print out either image index information, or image information, much like 
WordPress is either displaying an index of posts, or an individual post.
<a href="http://dannyman.toldme.com/photos-flickr/rtfm/" rel="nofollow ugc">There are hooks</a> 
for the full image index, an index of photo sets, set indexes and tag indexes, 
as well as pagination. There is no support yet for collections. Numerous bugs 
and ugly code are found throughout.

Social Images Widget is a no fuss, simple to use WordPress widget to display your latest Instagram photos.
Due to the changes in the way the Instagram API can be utilized, this widget can only be used to display your own own profile info and media. Inspired by the simplicity of the WP Instagram Widget (which is no longer maintained), this plugin uses sensible and simple markup, and provides no styles/css – it is up to you to style the widget to your theme and taste.

<h3>Setup / Instagram Authentication</h3>
This plugin requires that you authenticate your Instagram account. In order to do so:
<ul>
<li>We will redirect your request to the Instagram authorization URL. </li>
<li>If the you are not logged in to Instagram, you will be asked to log in.</li>
<li>You will then be asked if you would like to grant our Instagram application “LyraThemes Social Images Widget” access to your Instagram data.</li>
<li>Our application simply facilitates your access to the Instagram API, so you can use our plugin to access your Instagram feed. Please note, while your access data gets routed through our website at https://www.lyrathemes.com, it does not get stored at all in any form and is a simply a means to move the authentication data back to your own website.</li>
