Dynamic Image resizing in WordPress
"Dynamic Image Resize" is a WordPress (MU-)plugin that offers a shortcode and a template tag to resize images "on the flight" without the need of TimThumb, but with WP core functions.

If you are really not using Composer to keep your install up to date and don't have this plugin running as mu-plugin or included in your Theme, I recommend using the GitHub plugin updater. This plugin is compatible.
