This plugin is solution for well known flaw in WordPress architecture: 
automatic resizing uploaded images in each of registered media sizes.
Although price of hosting space is low and we have gigabytes available that can be issue if you have dozen 
(or more) registered sizes and because of that your backup files became larger than 10Gb. 
Sooner or later you will be in situation to download (or even worse – to upload) that backup file.
Our analysis shows that vast majority of resized thumbnails are not used anywhere in website. 
For typical theme with WooCommerce and additional 3 custom media sizes that percentage can be over 90%, 
with 6 custom media sizes it is over 96% !!!
Because of that developers are often uncomfortable with registering more media sizes trying to find 
some workarounds or violating design to accommodate existing similar sizes.
Purpose of this plugin is to eliminate that overhead and allow developer to register as many sizes as he needs.
It will intercept uploading process to prevent creation of thumbnails and intercept getters 
(wp_get_attachment_image_src(), get_the_post_thumbnail_url(), the_post_thumbnail(),…) to create thumbnail if needed. 
Additionally, it will register in database each created thumbnail allowing WordPress to delete it automatically 
when parent image is deleted.
<h3>Usage</h3>
At “Settings” tab of this tool you can pick individually for which size you want to enable or disable this functionality. 
Typically, you will enable it for all sizes.
Button “Delete” on “Utilities” tab will remove all thumbnails for sizes that are handled by this plugin. 
That will significantly reduce size of your “uploads” directory allowing new thumbnails to be recreated on demand.
Button “Regenerate all thumbnails” will remove existing and create new thumbnails for all your uploaded images.

Test your responsive website from the WordPress admin bar. This plugin uses the excellent <a href="http://lab.maltewassermann.com/viewport-resizer/" rel="nofollow ugc">Viewport Resizer bookmarklet</a> to add a responsive button to the WordPress admin bar. Once pressed you can easily test your site in a range of common viewport sizes (e.g. iPhone, Tablet and Desktop).
The plugin is handy for testing during development and also for writers and editors to preview their content on different devices.

I first heard about this plugin via the WordPress Plugins A to Z podcast. 
The name was catchy, so when I found myself doing responsive styling work today, I thought I'd try it out. 
All I can say, is that the interface alone makes this plugin stand out.
Responsive coding can be painful, but this plugin adds order to what can become a nightmare of manually resizing your browser window.
5 stars from me. Very nice.



Slick UI makes responsive testing more fun

Viewport resizing comes to the WordPress admin bar.
