The Twitter Gallery is a WordPress plugin for aggregating images/photos 
posted to twitter. The gallery script searches the public twitter feed 
for photos and images sent by users from around the world.
The initial release supports images posted to twitpic.com, yfrog.com, img.ly, flic.kr, ow.ly/i and twitgoo.com
Everyone can have a photo included in the gallery by updating his/her 
twitter status with a message that includes (one or more) images uploaded to either of the 6 services mentioned above and the twitter hash tag 
 # which is fully customizable through the administration dashboard.
Requirements
<ul>
<li>PHP 5.2.0 or newer</li>

Every time a page reloads to submit a form, a puppy dies. This plugin is the saviour of puppies.
Grunion Ajax submits a <a href="https://wordpress.org/extend/plugins/grunion-contact-form/" rel="ugc">Grunion Contact Form</a> using Ajax. It makes it super fast for visitors to submit a form.
The Grunion Ajax Javascript file is only loaded if the post or page in question includes the Grunion <code>[contact-form]</code> shortcode, so it’s efficient too.
The only caveat, Ajax submission has not been tested for Grunion Forms included in a widget.
