Provide visitors to your site the the option of increasing or decreasing the size of text by clicking on an icon which represents larger or smaller text.
Usage is simple. You can insert the code <code><?php if(function_exists('wptextsizerincutil')) { wptextsizerincutil(); } ?></code> where ever you would like the icons to appear.
NOTE: Some text will not resize if it uses an absolute size (pt) rather than a relative size in the CSS. This plugin will only resize text elements within the “content” div tag. If you are not using a div tag called “content” this plugin will not work for you.NOTE: Some text will not resize if it uses an absolute size (pt) rather than a relative size in the CSS.

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.
