Based on the wildly popular CatchMyFame.com Before/After jQuery plugin, the Joomla Before/After plugin provides 100% of the functionality in a non-commercial content plugin.
Use it anywhere you want, as many times as you want. In articles, category descriptions, modules - anywhere Joomla processes content plugins.
The plugin provides default settings, plus the article author can override each of the default settings in the image wrapper using data attributes. Full instructions are in the plugin configuration page. Additionally, I've implemented the Touch-Punch plugin, so this works on touch devices such as iPad, iPhone and Android tablets and phones.
I wrote this on commission, and my client waived his option for copyright because he believed as I do - that this plugin will benefit the Joomla community. Anyone who is familiar with me or my extensions knows that I love free.
All of the Before/After jQuery plugin options are present in the Joomla plugin configuration as defaults
All of those same configurations can be overridden using data attributes
