I hope the examples make it all a bit clearer. ReReplacer! can really come in handy for all sorts of site manipulation without having to hack the Joomla! core or components.
This component is been edited very well! loads of updates and really good future's.
The "piclens" support is awesome.
However there is 1 thing that is not completed, the multiple upload future that's important for me is not working as it should be in my eyes. I hope this will get developed in the future.
