WordPress plugin which displays responsive stage based on browser width:
<ol>
<li><code>>= 960px</code></li>
<li><code>768px - 959px</code></li>
<li><code>480px - 767px</code></li>
<li><code><= 479px</code></li>
</ol>
This helps in building CSS media queries, as you can quickly see what stage you are in when resizing your browser.
Options include ability to switch which corner the flag is displayed in, colors (so as to be distinguishable 
from your design), as well as whether to show only to admin or not.

BC Responsive Images is a WordPress shortcode plugin to enable editors and developers to automatically generate and manage <a href="http://responsiveimages.org/" rel="nofollow ugc">Responsive Images</a> via the WP Editor and within template files.
Originally created by Burfield’s team of <a href="http://www.burfieldcreative.co.uk" rel="nofollow ugc">Bath WordPress Designers</a> for internal use, we have subsequently released it as a Plugin with the following features
<ul>
<li>Mobile first – utilizes the excellent <a href="http://jquerypicture.com/" rel="nofollow ugc">jQuery Picture Plugin</a> to serve appropriately sized images only when required.</li>
<li>Resizes images on-the-fly – powered by the superb <a href="https://github.com/humanmade/WPThumb" rel="nofollow ugc">WPThumb Plugin</a> (where available) to avoid the dreaded “Regenerate Thumbnails” issue. Falls-back to WP Core images.</li>
<li>Fully featured shortcode <code>[brimg]</code> to allow editors to create Responsive Images within posts.</li>
<li>Powerful and customisable template function <code>brimg()</code> for developers to make use of in templates.</li>
<li>Simple yet powerful – set default breakpoints in the Plugin settings but still have the power to define your own on a case-by-case basis.</li>
</ul>
