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
before uploading.
