Asikart RemoteImage for Joomla 2.5 and 3.x has become one of my favorite Joomla extensions. It really user friendly and it takes the hassle out of adjusting, uploading and managing images files in Joomla. You can easily change image dimensions and even enhance or customize images -- all from within a Joomla article or in the Joomla backend. RemoteImage is a freely available extension. In this tutorial, I'll show you how you can install it and what the main features are.
This image management tutorial is an addition to the Joomla 3 Beginner's Guide by Eric Tiggeler (Packt Publishing 2013).
