Imsanity的作者是Exactly WWW，目前有300,000+个有效安装。已经Tested with 5.4.1版本的wordpress。
Imsanity automatically resizes huge image uploads down to a size that is
more reasonable for display in browser, yet still more than large enough for typical website use.
The plugin is configurable with a max width, height and quality. When a contributor uploads an
image that is larger than the configured size, Imsanity will automatically scale it down to the
configured size and replace the original image.
Imsanity also provides a bulk-resize feature to selectively resize previously uploaded images
to free up disk space.
This plugin is ideal for blogs that do not require hi-resolution original images
to be stored and/or the contributors don’t want (or understand how) to scale images
Automatically scales large image uploads to a more “sane” size
Bulk-resize feature to selectively resize existing images
Allows configuration of max width/height and jpg quality
Optionally converts BMP files to JPG so image can be scaled
Option to convert PNG files to JPG format for higher compression
Once enabled, Imsanity requires no actions on the part of the user
Uses WordPress built-in image scaling functions
Imsanity is available in several languages, each of which will be downloaded automatically when you install the plugin. To help translate it into your language, visit http://translate.wp101.net/projects/wp-plugins/imsanity
