## 外掛說明

By default WordPress forces all thumbnails be set to a quality level of 82. But 
what if you want to change that? Sure the
 jpeg qualtiy filters exist if you want
to code in a value, but they affect all JPEG thumbnails which may not be desirable.

For example you might want a blog background to be of a lower quality, hence lowering
the filesize and increasing the speed
 of which the page loads.

By using the JPEG Quality Settings plugin you can now customize the quality based
on whatever values you want.

## 安裝方式

Install in the usual WordPress way. Reconmended to use the plugin directory from
inside your WordPress install.

 1. Upload the plugin files to the `/wp-content/plugins/plugin-name` directory, or 
    install the plugin through the WordPress plugins screen directly.
 2. Activate the plugin through the ‘Plugins’ screen in WordPress
 3. Use the Settings->JPEG Quality screen to configure the plugin
 4. (Make your instructions match the desired user flow for activating and installing
    your plugin. Include any steps that might be needed for explanatory purposes)

## 常見問題集

  Does this affect any existing thumbnails?

No, you will need to install a plugin to regenrate thumbnails. Many good free options
exist.

  Can my theme provide default options?

Yes! By taking advantage of the filters installed. For example:

    ```
    `
    ```

add_filter(‘jpegquality_my_blog_size’, ‘mytheme_myblogsize_quality’);

function mytheme_myblogsize_quality(){
 return 10; } `
