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.
Update 1.2 - fix coding error which affected starting position
All of my extensions are free and none of my extensions display advertisements or links to my sites or services. If you feel that I have blessed you, then you can bless me by making a contribution to fund future development. Visit the "Website" link to make a contribution.
