-Allows you to regenerate your thumbnails after changing the thumbnail sizes.
+Allows you to regenerate your thumbnails after changing the thumbnail sizes or switching themes.
 
 == Description ==
 
-Regenerate Thumbnails allows you to regenerate the thumbnails for your image attachments. This is very handy if you've changed any of your thumbnail dimensions (via Settings -> Media) after previously uploading images or have changed to a theme with different featured post image dimensions.
+Regenerate Thumbnails allows you to regenerate all thumbnail sizes for one or more images that have been uploaded to your Media Library.
 
-You can either regenerate the thumbnails for all image uploads, individual image uploads, or specific multiple image uploads.
+This is useful for situations such as:
 
-See the [screenshots tab](http://wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/) for more details.
+* A new thumbnail size has been added and you want past uploads to have a thumbnail in that size.
+* You've changed the dimensions of an existing thumbnail size, for example via Settings → Media.
+* You've switched to a new WordPress theme that uses featured images of a different size.

+** WP-CLI **
+
+If you have command line access to your server, I highly recommend using [WP-CLI](http://wp-cli.org/) instead of this plugin as it's faster and can be run inside of a `screen`. For details, see the documentation of it's [regenerate](http://wp-cli.org/commands/media/regenerate/) command.
+
+** Jetpack's Photon Module **
+
+[Jetpack](http://jetpack.me/) is a plugin by Automattic, makers of WordPress.com. It gives your self-hosted WordPress site some of the functionality that is available to WordPress.com-hosted sites.
+
+[The Photon module](http://jetpack.me/support/photon/) makes the images on your site be served from WordPress.com's global content delivery network (CDN) which should speed up the loading of images. Additionally it can create thumbnails on the fly which means you'll never need to use this plugin.
+
+I personally use Photon on my own website.
+
+*Disclaimer: I work for Automattic but I would recommend Photon even if I didn't.*
