Great plugin! Installed without problems (Joomla-3). A good arsenal of options display the original image. Simple and easy to use. Of wishes, it would be good to add a watermark to overlay, as well - rating Excellent!
Just add an image to your article, resize it and you're done. I couln't be easier.
A real thumbnail is automatically created and stored, so the plugin is also very traffic-friendly.
In addition the developper is very helpful and responsive.
Great plugin, thank you very much!
