Automatically compress you content images into a big sprite, decreasing web page load time.

== Description ==
  The idea of combining images into a larger one and displaying this using CSS tricks has been around for awhile. There are a couple big benefits to doing this: First it reduces the number of HTTP requests that the browser has to make, by combining say 5 images into 1 big image, the number of image requests has been reduced by 4. This can increase the effeciency of page loading and you can see gains in the speed at which your page is loaded.
  cSprites will enable you to compress all of the images in your content into one big image, called a sprite and display this in parts. Thus the user will only have to make 1 request rather for all your images.

== Frequently Asked Questions ==

= I see some parts of other pictures in the image =

You MAY NOT use padding on the image if you would like to use cSprites, this is because the images are tightly packed and when you use padding parts of other images may show through. Wrap the img tag in a div or other element and add some padding to that.

= I am getting PHP errors =

You MUST be running PHP >= 5.0 and have GD library

= I am running PHP 5.0 and I still get PHP errors =

Make sure that you have this line in your php.ini file: `allow_url_fopen = ON`

== Release Notes ==
* **v0.482**
* Added options to include/exclude certain image types from processing
* Fixed the PNG compression (was not working before)
* **v0.482**
* fixed regex not matching single quoted html attributes
* **v0.481**
* fails much more gracefully, if cSprites requirements are not met
* **v0.48**
* fixed support for relative image urls
* **v0.47**
* added support for relative image urls
* added new option in administrator to clear the cache manually
* added a reset function to the cSprite core, might be applicable in the future
* **v0.46**
* Hook architecture was still broken. Now shouldn't mess up you post orders.
* **v0.45**
* Did a full rewrite of the hook architecture, I got it totally wrong on previous versions. Now scans the full WP Loop
and processes it prior to displaying the content. In previous versions I was using *the_posts* hook and this was failing
because many other plugins will also call this and we only want to scan the content. Now we use the *loop_start* hook.
* **v0.43**
* Fixed cache, wasn't working at all for images. Now is MUCH faster than before.
